由MLA144长猿淋巴肉瘤T淋巴细胞系产生的T细胞生长因子被分离为mr16300和mr14300两种分子形式,分别纯化了32000倍和82000倍,这两种分子形式共同构成了起始材料的大部分生物活性。生物活性的总体恢复为50%。这是通过一系列色谱步骤完成的,包括反相高压液相色谱。纯化的蛋白质具有相当的特异性活性,并且在浓度低于约18 pM (300 fg/ml)的情况下,每种蛋白质都能维持T细胞生长因子依赖的人T细胞系的DNA合成。
T cell growth factor produced by the MLA144 gibbon ape lymphosarcoma T lymphocyte line was separated into two molecular forms of Mr16,300 and Mr14,300 which were purified 32,000-fold and 82,000-fold, respectively, and which in combination constitute the majority of biological activity of the starting material. The overall recovery of biological activity was 50%. This was accomplished with a series of chromatographic steps including reverse-phase high pressure liquid chromatography. The purified proteins are of comparable specific activities and each maintains the DNA synthesis of T cell growth factor-dependent human T cell lines at concentrations of less than approximately 18 pM (300 fg/ml).
