Antigenic similarity between squamous cell carcinoma of horn (horn cancer) and normal bovine foetal tissues.
Normal bovine foetal (liver and skin) and horn cancer tissue antigens were examined using double diffusion agar gel precipitation and immuno-electrophoretic tests to detect any cross reactivity among them. Rabbit horn cancer antisera absorbed with normal bovine liver, skin and horn core epithelium antigens, when tested with foetal skin and liver (4 to 6 months of gestation), revealed the presence of 2 foetal antigens in horn cancer. Immuno-chemically 2 of the horn cancer antigens were found to be identical to the bovine foetal antigens.
