[Demonstration of antigen associated with human breast cancers].
The insoluble pellet of human mammary carcinomas was solubilized by an acid buffer. Antiserum prepared with this acidosoluble fraction, after suitable absorption gave one precipitin line with the immunizing extracts: this line is different from those given by the tumor associated antigens actually known. The same antiserum reacted only with sections of human mammary carcinomas by immunofluorescence . It did not stain sections of normal mammary glands or benign mammary diseases. Reactivity with cancers of other organs was absent or doubtful. Hence it is likely that an antigen associated to human mammary carcinomas was characterized.
