Study on the complement-dependent cytotoxic effect of the sera of hamsters bearing transplanted melanoma

Complement-dependent cytotoxic effect of the sera of hamsters bearing transplanted melanomas: melanotic and amelanotic, was examined in relation to isolated melanocytes of these melanomas. A specific, cytotoxic effect, ranging 34-47% of the sera of hamsters with both types of melanomas in relation to the cells of these tumors was found. No relationship between the biological properties of melanoma and cytotoxic activity of serum was noted.
