The major envelope glycoprotein of bovine leukemia virus was isolated by lectin-bound Sepharose and DEAE-cellulose column chromatography. This protein was shown to have a molecular weight of about 41,000 and to lack detectable immunological cross-reactivity with glycoproteins of other oncornaviruses. Sera obtained from 100% of cattle examined with clinically diagnosed lymphosarcoma contained high-titered antibody to 125I-labeled bovine leukemia virus glycoprotein, whereas sera from animals in a disease-free herd were antibody negative.
通过凝集素结合的琼脂糖凝胶和二乙氨基乙基纤维素柱色谱法分离出牛白血病病毒的主要包膜糖蛋白。该蛋白的分子量约为41,000,并且与其他肿瘤病毒的糖蛋白缺乏可检测到的免疫交叉反应性。对临床诊断为淋巴肉瘤的所有受检牛(100%)采集的血清含有针对125I标记的牛白血病病毒糖蛋白的高滴度抗体,而来自无病牛群动物的血清抗体呈阴性。
