The work presents the results of experimental study of gamma interferon obtained by gene engineering techniques on the basis of Escherichia coli producer strains. The study has revealed that gamma interferon, whose molecular weight is 15 KD, due to intracellular proteolytic degradation shows the absence of some amino acids at the C-end of protein and is electrophoretically homogeneous, while its antiviral, antiproliferative and immunomodulating effects are less pronounced than those of gamma interferon with a molecular weight of 18 KD.
该研究展示了基于大肠杆菌生产菌株通过基因工程技术获得的γ干扰素的实验研究结果。研究发现,分子量为15KD的γ干扰素,由于细胞内蛋白水解降解,在蛋白质的C末端缺少一些氨基酸,并且在电泳上是均一的,但其抗病毒、抗增殖和免疫调节作用不如分子量为18KD的γ干扰素明显。
