We reported previously the partial purification of detergent-solubilized specific tumor rejection antigen of a chemically induced sarcoma, Meth-A. During the course of the study, rabbit antiserum against a partially purified specific tumor rejection antigen preparation was raised and rendered
We examined the host immune response to a tumor-specific transplantation antigen (TSTA) induced by Rous sarcoma virus (RSV) In vivo. In contrast to previous in vitro studies, the present investigation demonstrated in vivo host immunity of the TSTA 10-55 days after tumor inoculation. Immunity to the
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
A simple, reproducible and quantitative method for evaluating certain non-specific immunological inhibitors in a variety of biological fluids is described. Human lymphocytes were stimulated with PHA in the presence of colchicine. Phytohaemagglutinin stimulated a large percentage of cells and
There are many quantitative changes of serum protein and immunoglobulin fractions in patients with cancer of various sites, excluding those with leukemic and lymphoproliferative disorders. The commonest change in serum proteins of patients with neoplastic disease is a reduction in albumin
Tumor necrosis can be induced in transplanted mouse methylcholanthrene-induced sarcoma by a tumor necrosis factor in the serum of mice infected with bacillus Calmette-Guérin and given bacterial endotoxin. Sera from normal mice, endotoxin-treated mice, and mice infected with bacillus Calmette-Guérin
