BLOCKING AND REDISTRIBUTION ("CAPPING") OF ANTIGEN RECEPTORS ON T AND B LYMPHOCYTES BY ANTI-IMMUNOGLOBULIN ANTIBODY

Abstract
Antigen-binding T and B lymphocytes were studied by combined autoradiography and immunofluorescence; mouse spleen lymphocytes binding the antigens, [125I]MSH or [125I]TIGAL, were incubated with rhodamine-labeled anti-Ig reagents or with a rhodamine-labeled IgG fraction of anti-θ serum. B cells were identified as Ig+ or θ-, T cells as Ig- or θ+.
