Immunological studies on viral mouse leukemias Ⅰ. A study by precipitation ring test

Fluorocarbon extracted antigens from spleens and livers from normal and leukemia (lymphocytic and myelogenous) in C 58 mice were analysed by means of a precipitation ring test and the following results were obtained. The viral antigen extracted from C 58 leukemic mice was different from the antigen extracted from C 58 normal mice. The myelogenous leukemic antigen and lymphocytic leukemic antigen were not entirely different but shared a common antigenic component.
