The main purpose of this paper is to study the batch production of recombinant human interleukin-6(rhIL-6).
The cloned rhIL-6 gene is under the control of T7 promoter of pET30a vector and expressed in E. coli.
The ratio of expressed recombinant protein to total cell protein is more than 50%. The rhIL-6 molecular weight is 21,000, isoelectric point is 6.7. The purity of the rhIL-6 is more than 95%, and the activity of rhIL-6, determined by IL-6 dependent mice hybridoma cell line 7TD1 and MTT assay, is 0.35 ng/ml.
All results mentioned show that rhIL-6 meets the request of the middle scale production.
本文的主要目的是研究重组人白细胞介素-6(rhIL-6)的批量生产。
克隆的rhIL-6基因受pET30a载体的T7启动子控制,并在大肠杆菌中表达。
表达的重组蛋白与总细胞蛋白的比例超过50%。rhIL-6的分子量为21,000,等电点为6.7。rhIL-6的纯度超过95%,通过IL-6依赖的小鼠杂交瘤细胞系7TD1和MTT法测定,rhIL-6的活性为0.35 ng/ml。
上述所有结果表明rhIL-6符合中规模生产的要求。
