Abstract

Tumor-specific transplantation antigen (TSTA) was solubilized from cell membranes of sarcoma Meth-A with non-ionic detergent Nonidet P40. Soluble TSTA was partially characterized by chromatographic separation and electrophoresis. The antigen responsible for tumor rejection activity had a molecular weight of approximately 70,000 daltons in the presence of detergent and an electrophoretic mobility of alpha-globulin. TSTA was well separated from mouse histocompatibility antigen H-2 by a sequence of procedures, including gel filtration, lectin affinity chromatography, column electrophoresis, and rechromatography on agarose, showed only three major bands on polyacrylamide gel electrophoresis. TSTA was specific for sarcoma Meth-A.
