title: Specificities of anti-rabbit VH antibodies in mammalian and fowl antisera.
abstract: Antibodies against rabbit VH-determinants were produced by immunizing mammals and birds with rabbit IgG, IgA or VH. Most of the anti-VH produced in mammals was specific for allotype VH-determinants, but small amounts of antibody against non-allotype VH-determinants were also produced. By contrast the immunization of chickens led to the production of predominantly non-allotype VH antibody. Further analysis of the antibody specificity revealed the production of antibody against VH-determinants available in the intact immunoglobulin (H- + L-chain) as well as antibody reacting with determinants only accessible in the absence of L-chain. Antibody of the latter specificity prevailed after immunization with VH. The purified VH was not deficient in antigen determinants when compared with VH in the intact immunoglobulin (IgA). Unexpectedly, none of our chicken anti-rabbit VH antisera showed crossreactivity with VH from other mammalian species.
