[Comparative antigenic analysis of J-96 cell oncornavirus and Mason-Pfizer virus from a spontaneous monkey mammary tumor].

A comparative study of the antigenic structure of oncornavirus of J-96 cells and Mason-Pfizer virus (M-PVM) isolated from cells of M. rhesus spontaneous mammary tumour was carried out using immunodiffusion in agar, immune autoradiography and indirect immunofluorescence procedures. Immune rabbit serum to disrupted J-96 virus detected by agar immunodiffusion in preparations or purified virus three soluble antigens one of which was identical to group-specific M-PVM antigen.
