Demonstration of Thymus-Derived Cell Surface Antigens on Various Guinea-Pig Lymphoid Cell Populations by a Micro-Immune Adherence Technique.

A micro-immune adherence assay employing direct microscopic observation was used to detect the presence of thymus-derived cell antigenic specificities on guinea-pig lymph node cells, purified peritoneal exudate lymphocytes, and thymocytes using a heterologous burro anti-guinea-pig thyrnocyte serum. A method is described for the direct determination of thymus-derived cell specificity of anti-lymphocyte sera. [ABSTRACT FROM AUTHOR]
