本文应用酶联免疫吸附技术对ＩＬ－６／２融合蛋白（ＦＰＩＬ－６／２）进行了定性、定量分析，测定其等电点，并对该蛋白的表位、柔性和抗原性进行了计算机模拟。ＥＬＩＳＡ测试结果表明：融合蛋白ＩＬ－６／２含有ＩＬ－２和ＩＬ－６两个结构域，可分别与ＩＬ－２和ＩＬ－６单克隆抗体结合，且两个结合无明显空间排阻效应，这与计算机的表位、柔性和抗原性分析结果一致。从计算机模拟也可以看出ＦＰＩＬ－６／２的抗原性与ＩＬ－２和ＩＬ－６的一致性，而且接头区抗原性较低，这为该蛋白的实际临床应用提供了一定的保证。
In this paper, the IL-6/2 fusion protein (FPIL-6/2) was detected by enzyme-linked immunosorbent assay. The isoelectric point was measured and the epitope, flexibility and antigenicity of the protein were analyzed. simulation. The results of ELISA showed that the fusion protein IL-6/2 contained two domains of IL-2 and IL-6, which could bind to IL-2 and IL-6 monoclonal antibodies respectively, and there was no obvious space exclusion effect , Which is consistent with the computer’s epitope, flexibility and antigenicity analysis. The computer simulation also shows that the antigenicity of FPIL-6/2 is consistent with that of IL-2 and IL-6, and the antigenicity of the linker region is low, which provides a guarantee for the practical clinical application of FPIL-6/2.
