Metallothionein 2A (MT2A ) 是能被暴露导致到有毒的金属的小压力反应蛋白质。它高度在乳癌房间被表示。在这研究,编码人的 MT2A 蛋白质的 cDNA 在 Escherichia 关口 i 被表示为谷胱甘肽 S-transferase (GST ) 熔化蛋白质。Recombinant MT2A 蛋白质被装载到 12% 钠 dodecylsulfate-polyacrylamide 胶化上并且由电气泳动分开了, recombinant 蛋白质被染色的 Coomassie 蓝色和 33 kDa recombinant GST-MT2A 熔化蛋白质设想乐队从胶化被切掉。胶化片被切碎并且过去常产生 polyclonal 反时代。对 MT2A 蛋白质的兔子的免疫允许高 titer polyclonal 抗血清的生产。这新 polyclonal 抗体在西方的污点分析认出了 recombinant MT2A 蛋白质。这便宜抗体将为在各种各样的免疫分析的察觉是有用的。
Metallothionein 2A (MT2A) is a small stress response protein that can be induced by exposure to toxic metals. It is highly expressed in breast cancer cells. In this study, the cDNA encoding the human MT2A protein was expressed as glutathione S-transferase (GST) fusion protein in Escherichia coli. Recombinant MT2A proteins were loaded onto 12% sodium dodecylsulfate-polyacrylamide gel and separated by electrophoresis, the recombinant protein was visualized by Coomassie blue staining and the 33 kDa recombinant GST-MT2A fusion protein band was cut out from the gel. The gel slice was minced and used to generate polyclonal antisera. Immunization of rabbit against MT2A protein allowed the production of high titer polyclonal antiserum. This new polyclonal antibody recognized recombinant MT2A protein in Western blot analysis. This low-cost antibody will be useful for detection in various immuno-assays.
