摘要: NUMEROUS attempts have been made to solubilize tumour specific transplantation antigens (TSTA) of carcinogen-induced neoplasms and virus-specified (VSTA) from the cell membranes DNA RNA virus-induced neoplasms1–6. Usually, yields biologically active materials are low labile. Soluble antigenic obtained transplantable hepatomas1,2 purified by gel filtration were found limited biological activity. Although immunological specificity was preserved, assays used relatively precision. Tumour rejection, a major function both TSTA VSTA, not observed.
