title: Identification of proliferating lymphocyte subpopulations by combined alkaline phosphatase anti-alkaline phosphatase (APAAP) staining and autoradiography.
abstract: An improvement in the classification of proliferating ([3H]thymidine incorporating) lymphocyte subpopulations in mitogen- or antigen-stimulated microcultures is described. The binding of subset-specific monoclonal antibodies is detected by the alkaline phosphatase anti-alkaline phosphatase method (APAAP). There are two advantages compared to the peroxidase anti-peroxidase (PAP) method; (1) endogenous enzyme (peroxidase) activity exhibited by some cells causes no interference, and (2) the red alkaline phosphatase staining obtained with new fuchsin provides a far superior contrast to silver grains than conventional peroxidase staining.
