233 Selecting a polyclonal programme The generation of a polyclonal antibody is dependent on two main factors, after which biology takes over. 1. The first parameter involves foreignness a sequence alignment between your antigen s sequence and the host animal is highly recommended before starting an immunization programme. 2. The second parameter is availability of pure antigen in sufficient quantity to elicit an immune response in the host. Please use the following flowchart to select the best polyclonal strategy. What s a standard antibody programme? Unfortunately antibody suppliers all have their own standard programmes. Our standard programme exceeds those of other suppliers. Our rabbit polyclonal standard programme: 87-day protocol 4 immunizations 4 bleeds shipping included As antibody production is a natural phenomenon that follows a welldescribed time course, there is a direct dependence on antibody titre and programme duration. In general, the longer the programme, the better the antibody titre and antibody affinity. The following flowchart should help you select a polyclonal protocol Antigen sequence NO Homology with isoforms? YES Have antigen? MW > 10 kda, purified to > 80 %, 1 mg (rabbit Ab) NO Homology undesired? YES NO YES Send sequences to peptide.design@eurogentec.com for best peptide selection help Select best host based on - homology to antigen - amount of Ab required Select best host based on - homology to peptide seq - amount of Ab required Complete anti-protein antibody order form Complete anti-peptide antibody order form EUROGENTEC 2008 Catalogue > www.eurogentec.com > order@eurogentec.com

This can mean a purified protein if one is not limited by homology with protein isoforms. Protein antigens offer many epitopes, providing and increased chance of generating antibodies that are useful in a wide range of applications. The prerequisites are that the antigen be purified to > 80 % purity and that sufficient material be provided for immunization. For our standard 87-day rabbit programme, we recommend at least 100 µg of purified protein per injection per rabbit, which translates into 800 µg of purified antigen. Peptide antibody programmes are particularly useful for the selective targeting of an antigen isoform, by selecting a peptide region that is unique to the desired isoform, or for antibody programmes that are designed to detect post-translational modifications. Peptide antibodies are today a very viable alternative to anti-protein programmes. A peptide antibody programme offers the advantages of being able to immunize with highly purified material and to affinity purify the antibodies against the peptide. Single peptide versus Double X strategy The single peptide strategy is best suited for reproducing the previously documented success of a polyclonal production with a known peptide sequence. If you have already successfully generated antibodies using a particular peptide or if the scientific literature suggests that a particular peptide is useful for generating specific antibodies, Eurogentec recommends the single peptide approach. For the first-time generation of antibodies against a particular antigen, we recommend the Double X strategy. The Double X strategy involves the design of two peptides from the same antigen and immunizing the host animals with both peptides at the same time. This co-immunization more closely mimics the protein than a single peptide strategy and we have success rates in the 90 % in Western Blots using this technique.

Custom polyclonal antibody production Antibody titre evolution Antibody affinity evolution Exposure to a specific antigen will initiate the immune response and in the first phase will result in the production of IgM class antibodies. IgM antibodies are responsible for the first attempt at clearance by the host animal. Initially the serum antibody titre is composed mainly of low affinity and low titre of predominantly IgM type antibodies. A second exposure will trigger a faster response, on the order of hours to days, and will generate longer lasting IgG type antibodies. IgG antibodies are of higher titre and affinity than IgM antibodies. With the generation of IgG antibodies is the generation of memory cells to quickly inactivate further exposure to the same antigen. Each immune response is different however a general schematic of IgM and IgG antibody titre as a function of time is represented below. The second immune response is not only characterized by a faster immune reaction but also by antibodies with up to a 10,000 fold increased affinity for the antigen. This increase is due to random somatic hypermutation in the variable region of the light chain and the heavy chain during expansion of memory cells. The diversity of the specificity will increase amongst a single clone. A second mechanism occurs following the antigen binding: isotype class switching. It refers to a rearrangement of the genes coding for the heavy chains in memory cells. The loss of coding region causes a class switch from IgM to IgG, IgA and IgE. A combination of these two mechanisms, somatic mutation and clonal selection leads to affinity evolution. Affinity evolution can be monitored by a number of methods, below are the results from serum drawn at different time points during a 3-month polyclonal rabbit programme. The flatter the curves, the tighter the binding affinities. Evolution of IgM and IgG titres as a function of immunization and time Evolution of affinity during an 87-day anti-peptide polyclonal programme

Individually, each sequence is antigenic but, depending on the number of accessible residues in the interaction, the affinity will be either acceptable or too low. Currently, antibody affinities of 10-8 to 10-9 M can be expected for linear epitope, by calculating and analyzing the structure of each potential epitope. We will propose the most appropriate antigenic fragments that should exhibit such affinities. An epitope for each application As the structure of your protein may vary with each assay, an assay antigen specific analysis must be made to determine structural and interaction properties. Major factors leading to changes in the epitope structure are (1) denaturation by detergent and (2) chemical modification of the amino acids of the epitope, for example with fixatives or other chemicals. For your immuno-assay technique the most exposed epitope may not be your best choice. Depending on whether the antibody will be used on a native, a detergent-denatured or a fixative-modified structure of your protein, we shall select either a flexible or a more rigid region of the protein such as a turn or a helix. Increased flexibility is reported to lead to improved affinity, however, rigid structures can provide good epitopes more resistant to detergent denaturation. Additionally, sequences containing aromatic residues rather than highly polar amino acids may be selected if application conditions will involve the use of chemicals that react with polar moieties. Indeed, as long as they do not impair the fragment accessibility, hydrophobic residues could improve the affinity. The prediction of the best epitope is closely linked to the application for which the antibody will be used. The First Class programme what do we do? Using a consensus of epitope prediction procedures we characterize all potential linear epitopes. Then, in a second step, we calculate their structures and keep those whose characteristics are adequate to raise high affinity antibodies. In the third step, we select the fragment(s) that are the most likely to be useful in your immunoassay. What do we need? The accession number of the protein of interest and a complete description of the application in which you will use the antibody. Please complete the questionnaire on the corresponding order form. We include : Application specific peptide design 5 pre-immune rabbit sera for animal selection Synthesis of 2 peptides, 20-25 mg each Coupling of each peptide to a carrier protein Double X protocol in a 4-month program ELISA testing to monitor titer evolution Affinity purification of 5 ml of serum against each peptide Delivery of 15-20 mg of free peptide Remaining antisera All shipping costs Please note 100 µl of the different bleeds and 100 µg of the purified antibody will be shipped for testing prior delivery of the total volumes.
