Category: Antibody Protocols: Epitope Mapping Antibody Protocols

The simplest way to determine whether two monoclonal antibodies bind to distinct sites on a protein antigen is to carry out a competition assay. The assay can be used with antibodies that bind both conformational and linear epitopes, and it is most useful in the analysis of monoclonal antibody specificity because polyclonal sera typically recognize multiple different epitopes. - [Read Epitope Mapping by Competition Assay Protocol]

Polyclonal antibodies can be isolated from animal plasma or serum using the procedure described in this protocol. The Gradiflow BF400 instrument has two liquid streams that circulate through a separation cartridge positioned between two electrodes and composed of three hydrogel polyacrylamide membranes, which define the channels for the two sample streams. The central membrane forms a physical barrier between the two streams. - [Read Preparation of Polyclonal Antibodies from Plasma or Serum Using the Gradiflow BF400]

Category: Immunology: B Cell Protocols

Describes procedures for measuring the capacity of purified B cells to undergo proliferation. The method centers on the use of polyclonal stimulating agents (mitogens) because these agents stimulate the majority of B cells and because the alternative (measurement of antigen-induced proliferation) requires the laborious procedures of isolating antigen-specific B cells (which are otherwise present in too low a concentration in whole B cell populations). - [Read Proliferative Assays for B Cell Function Protocol]

Immunoaffinity purification of antibodies is used to purify antigen-specific antibodies from a preparation of polyclonal antibodies.  Such purification is commonly needed in the production of antipeptide antibodies, where it is used to concentrate the desired antibodies and separate them from those raised against carrier proteins.  It is also used for the more general purpose of removing unwanted, nonspecific binding activity from polyclonal antibody preparations. - [Read Purification of Antibodies on an Antigen Column Protocol]
