title: Detection of antibody, idiotype, and anti-idiotype forming cells by in situ immunocytochemical staining.
abstract: Methods are described for the immunocytochemical staining of cryostat sections of lymphoid tissue with enzyme conjugates of antigen, idiotype (Id) and anti-idiotype. Results established this as a useful approach, for simultaneously detecting Id and anti-Id antibody forming cells (AFC) in situ. As a model, the 5AF6 Id family associated with the BALB/c mouse antibody response against the p-azophenyl-arsonate (Ar) epitope was examined by two-color immunocytochemical staining, allowing the simultaneous detection of both Id+ and Id- anti-Ar AFC. Spleens from mice secondarily immunized with Ar antigen but not normal mice contained anti-Id AFC stained with the 5AF6 Id but not with another immunoglobulin of the same isotype. A sequential staining method was developed which allowed the detection of both Id and anti-Id AFC in the same tissue, thus providing a means of examining Id and anti-Id antibody networks in intact lymphoid tissues.
