Antigenic Properties of Methylcholanthrene-induced Tumors in Mice of the Strain of Origin

Experiments are described in which it was shown that immunity of C3H-He mice resulted following ligation and atrophy of methylcholanthrene-induced sarcomas which arose in mice of this inbred strain. The results are discussed in relation to previously reported experiments in which C3H-He mice were not immunized against mammary carcinoma by similar methods.
