title: Inhibition of immune responses in vitro by specific antiserums to Ia antigens.
abstract: Mouse antiserums prepared against Ia antigens, which are products of I (immune response) region genes of the H-2 complex, can inhibit both primary (immunoglobulin M) and secondary (immunoglobulin G) immune responses in vitro by mouse spleen cultures to heterologous erythrocytes. Antiserums directed specifically at products of either the H-2K or H-2D loci have no effect on this response.
