Results are displayed as a box-and-whisker plot (S/R, sample to reference ratio). Antigen-specific IgY, IgM or IgA antibody levels were determined in 20-fold diluted sera collected from 12 day-old individual animals. NHC flagellin-specific antibody levels in the groups immunized with (A) 40 μg of NHC protein and (B) 20 μg of NHC protein, both compared to levels in the solvent injected control group. As a result of the procedure a secondary antibody is generated which specifically recognizes rabbit IgG light chains.Horseradish peroxidase conjugated Goat anti Chicken IgM antibody ( AAI27P) used for the evaluation of flagellin specific IgM response in exposed chickens by ELISA.Īntigen-specific serum antibody responses. Only antibodies specific to rabbit IgG light chains will pass through the column whereas, antibodies cross reacting with sheep or bovine IgG light chains will bind and stay adsorbed to the matrix. The mixture of secondary antibodies (containing secondary antibodies against rabbit IgG light chains, sheep IgG light chains and bovine IgG light chains, for example) is passed through a matrix containing immobilized serum proteins from potentially cross reactive species (in this case sheep and bovine light chains). ![]() Pre-adsorption (also referred to as cross-adsorption) is an extra step introduced to increase the specificity of an antibody. The pre-adsorption process reduces the risk of cross reactivity between the secondary antibody and endogenous immunoglobulins present on cell and tissue samples. ![]() Pre-adsorbed secondary antibodiesare ideal for multi-color experiments when several primary antibodies and their corresponding secondary antibodies are used simultaneously. Pre-adsorbed secondary antibodies - ideal for eliminating species reactivity
