为人白细胞介素-10(hIL-10)的理论研究和临床应用研究提供材料。方法:利用基因工程技术,将hIL-10cDNA克隆在大肠杆菌表达载体中,在大肠杆菌中高效表达含凝血酶识别序列的hIL-10的融合蛋白。表达蛋白经凝酶消化后,可去除MS2细菌蛋白。结果:获得高纯度的非融合型rhIL-10。结论:活性分析表明rhIL-10具有抑制LPS刺激的外周血单个核细胞产生IL-6的能力。
Human interleukin-10 (hIL-10) theoretical research and clinical application of research materials. Methods: The hIL-10 cDNA was cloned into E. coli expression vector and the fusion protein of hIL-10 with thrombin recognition sequence was highly expressed in E. coli. After the protein is digested by the enzyme, MS2 bacterial protein can be removed. Results: High purity non-fusion rhIL-10 was obtained. CONCLUSION: The activity analysis shows that rhIL-10 has the ability to inhibit the production of IL-6 by LPS-stimulated peripheral blood mononuclear cells.
