title: Preparation of cell-free feline oncornavirus-associated cell membrane antigen.
abstract: Cell-free feline oncornavirus-associated cell membrane antigen (FOCMA) was prepared from a feline lymphoblastoid cell line of tumor origin (FL-74). Membrane fractions, separated on sucrose density gradients, and papain-solubilized products were found to contain FOCMA as determined by their capacity to inhibit reference cytotoxic cat antisera.
