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.
无细胞猫肿瘤病毒相关细胞膜抗原（FOCMA）是从一株肿瘤来源的猫淋巴母细胞系（FL-74）制备而来。通过蔗糖密度梯度离心分离得到的膜组分以及木瓜蛋白酶增溶产物，经检测其抑制参比细胞毒性猫抗血清的能力，发现均含有FOCMA。
