本文制备了细胞蛋白标准及其抗血清 ,采用ELISA方法测定了重组人组织型纤溶酶原激活剂 (rt -PA)中细胞蛋白含量 ,结果表明该法灵敏度好 ,能检测出产品中的微量细胞蛋白 ,对三个rt -PA样品检测合格。
In this paper, cell protein standards and antisera were prepared. The protein content of recombinant human tissue plasminogen activator (rt-PA) was measured by ELISA. The results showed that the method has good sensitivity and can detect trace amounts Cell proteins were tested for three rt-PA samples.
