The Den gives good support for the students who are preparing for higher studies. Useful for Biochemistry, Biotechnology, Microbiology, Molecular biology, botany and zoology students.
Top schools and universities offer free online coursework in various topics through a program called open courseware (OCW). First developed by Massachusetts Institute of Technology, the programs are the same as a paid course at a traditional college. A person does not earn college credit for the course.
Opencourseware was developed with the mission of sharing information and helping people improve their mind. Based on the principles of co-existence and co-prosperity, many countries around the world are following the guidelines originally conceived by Massachusetts Institute of Technology. Almost any topic of interest can be learned free of charge online, from French to biochemistry. The following schools have OCW programs for a person seeking training in biochemistry.
Massachusetts Institute of Technology offers a graduate level course in biochemistry. Lecture notes are provided on the major concepts of biochemistry, kinetics, the Chemical Kinetics Simulator 1.01, chemical thermodynamics, chemical equilibrium and mystery protein. The program focuses on the analytical methods used to dissect biological issues. Students study the structure of proteins in the regulatory, catalytic and binding stages.
The University of Arizona offers The Biochemistry Project, which consists of several free biochemistry courses online. Students review the basics of biochemistry, including molecules, amino acids, the clinical correlates of pH levels, acids and bases, enzymes and catalysts energy and metabolism. The courses provide multiple problem sets, or tests, for students to assess how well they know the presented material.
The University of Arizona has recently expanded its offerings to include chemistry of amino acids. Other OCW courses are cell biology, immunology, Mendelian genetics and molecular biology.
The University of Akron offers an overview of concepts in biochemistry that covers different areas of biochemistry, including alpha helix protein, acetyl co-enzyme A, amylase, beta sheet protein, collagen, hammerhead ribozyme, heme and FAD. An interesting feature of the site is an interactive collection of animated files that display molecules being rotated so students can observe their geometry. The site includes a chemical database and a periodic table of elements.
The biochemistry course at Texas A&M University offers students lecture notes to present material that is similar to what would be learned in a traditional lecture course. The topics covered in class and through the lecture notes include bioenergetics, introductions to metabolism, glycolysis, pentose phosphate pathway, biological reduction-oxidation reaction (redox) reactions, glycogen metabolism and the citric acid cycle.

Enzyme immunoassay combine the specificity of antibodies with the sensitivity of simple spectrophotometric enzyme assays by using antibodies or antigens coupled to an easily assayed enzyme that also possesses a high turnover number. ELISA is replacing RIA, despite the latter already being established, extensively automated and sometimes more sensitive.
ELISA may be used for assaying antigens by either a competitive or a double antibody method and for assaying a specific antibody by an indirect method. All these methods require the preparation of a calibration curve during the assay.
The ELISA divided into three types, they are
a) Competitive method b) Double-antibody method c) Indirect method
a) Competitive method: A mixture of a known amount of enzyme - labelled antigen and an unknown amount of unlabelled antigen is allowed to react with a specific antibody to attach to a solid phase. After the complex has been washed with buffer, the enzyme substrate is added and the enzyme activity measured. The difference between this value and that of a simple lacking unlabelled antigen is a measure of the concentration of unlabelled antigen.
Major disadvantage: this method is that each antigen may require a different method to couple it to the enzyme; this is not so for the double-antibody method.
b) Double-antibody method: The unknown antigen solution is reacted with specific antibody attached to a solid phase, washed and treated with enzyme labelled antibody (directed against a different epitope, if monoclonal antibodies). After a further wash the enzyme substrate is added. The amount of enzyme activity measured under standard conditions directly proportional to the amount of antigen present. Advantage: It is that only one procedure required coupling the enzyme to all preparations.
c) Indirect method: The method may be used to measure antibody levels. The putative antiserum is reacted with specific antigen attached to a solid phase. Any specific antibody molecules bind to the antigen and all other material is washed away. Exposure of the complex to enzyme labelled anti-immunoglobulin antibody results in binding to any specific antibody molecules adsorbed from the original serum. The complex is washed and the substrate for the enzyme added, resulting in activity proportional to the amount of specific antibody in the serum.
ELISA, in which enzyme labelled antibody binds an antigen, leading to substrate breakdown and colour change, can be used to detect primary antigen-antibody reactions
ELISA uses an enzyme for labelling rattier than a radioisotope. Like the radioisotopes, the enzyme is covalently coupled to the antibody, in principle, this is the only difference between ELISA and RIA. ELISA measures bound enzyme activity rather than bound counts per minutes. Quantification requires measuring the colour intensity of the colored products generated by the enzyme and added substrate. The intensity of the colour is equivalent to the amount of labeled antibody bound to antigen. ELISA has replaced RIA in many clinical and basic science laboratories. RIAs are potentially hazardous and tedious, require bookkeeping, and involve radioisotopes. These reasons combined with the commercial availability of plate readers that can be measure the absorbance of 96 wells in less than a minute, account for ELISA's growing popularity. ELISA and RIA are similar in sensitivity. Theoretically, ELISA can be more sensitive than RIA because each enzyme molecule can generate hundreds of thousands of colored product molecules that can be measured. In contrast, 12S I molecule decays only once. Once application of ELISA is to detect the presence and titre of specific antibody for the AIDS virus.
Applications of ELISA:
When an antigen is introduced into the circulatory system of a higher vertebrate, it stimulates specific B-lymphocytes to produce antibodies. The antibodies are the immunoglobulins and they circulate in the blood serum.
When the immune system of an animal encounters a new antigen, it responds to specific antigenic determinants called 'epitopes' located on the antigen. Thus, a protein antigen may possess several epitopes and would induce the formation of several different antibodies, each specific for one epitope. Such a polyclonal antibody response facilitates the localization, phagocytosis and complement-mediated lysis of antigens.
For most reasearch, diagnostic and therapeutic purposes, "Monoclonal antibodies", derived from a single clone and thus specific for a single epitope are preferable.
In 1975, "Georges Kohler" and "cesar Milstein" devised a method for preparing monoclonal antibody, which quickly became one of the immunology's key technologies. These work got Nobel Prize in 1984.
Basic concept Principle on the monoclonal antibodies production:
By fusing a normal activated, antibody producing B-cell with a myeloma cell(a cancerous plasma cell), they were able to generate a hybrid cell, called a 'hybdridoma', that possessed the immortal-growth properties of the myeloma cell and secreted the antibodies produced by the B-cell. The resulting clones of hybridoma cells,which secrete large quantities of monoclonal antibodies can be cultured indefinitely. The development of techniques for producing monoclonal antibody gave immunologists a powerful and versatile research tool.
Production &Selection of hybridoma cells:
One common method requires the use of myeloma cells that are deficient (because of previously selected mutation) for one of the nucleotide salvage pathways, making them unable to grow in HAT medium (named for its three components -Hypoxanthine, Aminopterin, and Thymidine). If the mixture of hybridomas and unfused parental cells is placed in this medium, the parental myeloma cells can not survive. The B-cell X myeloma cells can survive because the B-cell contributes the missing enzyme for the salvage pathway. Although unfused B-cells are able to survive in HAT medium, these cells do not live for extended periods in vitro and thus die out.
HAT selection depends on the fact that mammalian cells can synthesize nucleotides by two different pathways; the denovo and the salvage pathways. The denovo path way, in which a methyl or formyl group is transferred from an activated form of tetrahydrofolate, is blocked by Aminopterin, a folic acid analogue. When the denovo path way is blocked, cells utilize the salvage pathway, which bypasses the aminopterin block by converting purines and pyrimidines directly intoYiucleotides for synthesis of DNA and RNA. The enzymes catalyzing the salvage pathway include Hypoxanthine-Guanine Phosphoribosyl transferase(HGPRT) and Thymidine kinase(TK). A mutation in either of these two enzymes blocks the ability of the cell to use the salvage pathway. HAT medium contains aminopterin to block the denovo pathway and hypoxanthine and thymidine to allow growth by the salvage pathway. Therefore, cells that lack either HGPRT or TK will die in HAT medium, because they lake the ability to use the salvage pathway to acquire essential intermediates for the synthesis of nucleic acids.
In hybridoma technology, the myeloma cells are actually double mutants. As mentioned above, they lack the enzyme HGPRTase and therefore are deselected in HAT. They have lost the ability to produce immunoglobulins (Ig- mutants).
Applications of Monoclonal Antibodies:
1. Improved diagnostic reagents: For the assay of wide range of compounds, including hormones, antibiotic interferons, and blood-clotting factors, antibody-antigen reactions are widely used. For blood typing and diagnostic microbiology, the ability of antibodies to agglutinate or precipitate cells have been used; the homogeneity of Monoclonal antibodies reduces reaction times and the likelihood of non-specific cross-reactions between the antibody and antigen is lessened by the use of Monoclonal antibodies. It is possible to diagnose pregnancy or ovulation more precisely with the Monoclonal antibodies.
2.Protein purification: Monoclonal antibody affinity columns are prepared by coupling monoclonal antibodies to a cyanogen bromide-activated chromatography matrix, for example, sepharose. Monoclonal antibodies immomabalized in this way are particularly valuable for the purification of proteins. Since the monoclonal antibodies has a unique specificity for the desired proteins, the level of contamination by unwanted proteins, usually, is very low. Even when the concentrating of the desired protein, in a mixture of proteins, is very low, Monoclonal antibodies has the capacity to combine with it and to remove the whole of it. For example, when the concentration of interferon was less than 0.02%, the anti-interferon monoclonal antibodies enable the recovery of 97% of the interferon by immunoaffinity chromatography.

Proteins are an important class of biological macromolecules present in all organisms. All proteins are polymers of amino acids. Classified by their physical size, proteins are nanoparticles (definition: 1-100 nm). Each protein polymer – also known as a polypeptide – consists of a sequence of 20 different L-α-amino acids, also referred to as residues. For chains under 40 residues the term peptide is frequently used instead of protein. To be able to perform their biological function, proteins fold into one or more specific spatial conformations, driven by a number of non-covalent interactions such as hydrogen bonding, ionic interactions, Van Der Waals forces, and hydrophobic packing. To understand the functions of proteins at a molecular level, it is often necessary to determine their three-dimensional structure. This is the topic of the scientific field of structural biology, which employs techniques such as X-ray crystallography, NMR spectroscopy, and dual polarisation interferometry to determine the structure of proteins.
Protein structures range in size from tens to several thousand residues Very large aggregates can be formed from protein subunits: for example, many thousand actin molecules assemble into a microfilament.
A protein may undergo reversible structural changes in performing its biological function. The alternative structures of the same protein are referred to as different conformations, and transitions between them are called conformational changes.

Description: For nearly a quarter century Molecular Biology of the Cell has been the leading cell biology textbook. This tradition continues with the new Fifth Edition, which has been completely revised and updated to describe our current, rapidly advancing understanding of cell biology. To list but a few examples, a large amount of new material is presented on epigenetics; stem cells; RNAi; comparative genomics; the latest cancer therapies; apoptosis (now its own separate chapter); and cell cycle control and the mechanics of M phase (now integrated into one chapter).
The hallmark features of Molecular Biology of the Cell have been retained, such as its consistent and comprehensive art program, clear concept headings, and succinct section summaries. Additionally, in response to extensive feedback from readers, the Fifth Edition now includes several new features.
It is now more portable. Chapters 1-20 are printed and Chapters 21-25, covering multicellular systems, are provided as pdf files on the free Media DVD-ROM which accompanies the book.* And for the first time, Molecular Biology of the Cell now contains end-of-chapter questions. These problems, written by John Wilson and Tim Hunt, emphasize a quantitative approach and the art of reasoning from experiments, and they will help students review and extend their knowledge derived from reading the textbook.
The Media DVD-ROM, which is packaged with every copy of the book, contains PowerPoint presentations with all of the figures, tables and micrographs from the text (available as JPEGs too). Also included is the Media Player, which plays over 125 movies and animations, videos, and molecular models all with voice-over narration. A new reader-friendly feature is the integration of media codes throughout the text that link directly to relevant videos and animations. The Media DVD-ROM holds the multicellular systems chapters (21-25) of the text as well.
By skilfully extracting the fundamental concepts from this enormous and ever-growing field, the authors tell the story of cell biology, and thereby create a coherent framework through which readers may approach and enjoy this subject that is so central to all of biology.

Theoretical basis of isoelectric point calculation,
Isoelectric point (pI) is a pH in which net charge of protein is zero. In case of proteins isoelectric point mostly depends on seven charged amino acids: glutamate (δ-carboxyl group), aspartate (ß-carboxyl group), cysteine (thiol group), tyrosine (phenol group), histidine (imidazole side chains), lysine (ε-ammonium group) and arginine (guanidinium group). Additonally, one should take into account charge of protein terminal groups (NH2 i COOH). Each of them has its unique acid dissociation constant referred to as pK.
Moreover, net charge of the protein is in tight relation with the solution (buffer) pH. Keeping in main this we can use Henderson-Hasselbach equation to calculate protein charge in certain pH:
- for negative charged macromolecules:
where pKn is the acid dissociation constant of negatively charged amino acid
- for positive charged macromolecules:
where pKp is the acid dissociation constant of positively charged amino acid
As you can see, only pH of buffer is variable in equations. If we successively change this value, finally we will find isoelectric point of analyzed protein. The knowledge of isoelectric point is of great significance in biochemistry (mainly in elecrophoresis and isofocusing techniques), because it allows to match proper environment before the experiment starts.
Generally, macromolecules are positively charged and on the other hand, above proteins isoelectric point, their charge is negative.For example, during electrophoresis, direction of proteins migration, depends only from their charge. If buffer pH (and as a result gel pH) is higher than protein isoelectric point, the particles will migrate to the anode (negative electrode) and if the buffer pH is lower than isoelectric point they will go to the cathode. In situation when the gel pH and the protein isoelectric point are equal, proteins do not move at all.
Using above formulae, we can calculate theoretical isoelectric point. The result will be almost surely different than real isoelectric point. It is mainly because many proteins are chemically modified (amino acids can be phosphorylated, methylated, acetyleted etc.), which change their charge. Problematic is also the occurrence of cysteines (negative charge) which can oxidise and form disulfide bond in protein. Therefore, they will become cystines, which do not express any charge.
Nevertheless, one can approximately calculate protein isoelectric point which is ± 0.5 of exact isoelectric point. The most critical moment during isoelectric point determination is usage of appropriate pK values. Unfortunately, there is no agreement in this matter. Each source gives different pKs. some are given below:
The isoelectric point (pI), sometimes abbreviated to IEP, is the pH at which a particular molecule or surface carries no net electrical charge.
Amphoteric molecules called zwitterions contain both positive and negative charges depending on the functional groups present in the molecule. The net charge on the molecule is affected by pH of their surrounding environment and can become more positively or negatively charged due to the loss or gain of protons (H+). The pI is the pH value at which the molecule carries no electrical charge or the negative and positive charges are equal.
Surfaces naturally charge to form a double layer. In the common case when the surface charge-determining ions are H+/OH-, the net surface charge is affected by the pH of the liquid in which the solid is submerged. Again, the pI is the pH value of the solution at which the surfaces carries no net charge.
The pI value can affect the solubility of a molecule at a given pH. Such molecules have minimum solubility in water or salt solutions at the pH which corresponds to their pI and often precipitate out of solution. Biological amphoteric molecules such as proteins contain both acidic and basic functional groups. Amino acids which make up proteins may be positive, negative, neutral or polar in nature, and together give a protein its overall charge. At a pH below their pI, proteins carry a net positive charge; above their pI they carry a net negative charge. Proteins can thus be separated according to their isoelectric point (overall charge) on a polyacrylamide gel using a technique called isoelectric focusing, which uses a pH gradient to separate proteins. Isoelectric focusing is also the first step in 2-D gel polyacrylamide gel electrophoresis.
