目的构建核转录因子κB抑制蛋白激酶(inhibitor of kappa B kinase,IKK)β真核表达载体,以便进一步探讨其生物学作用。方法从人正常肝细胞L02中提取RNA,并利用IKKβ特异性引物通过RT-PCR方法扩增了IKKβcD-NA,并克隆入pcDNA3载体中,构建重组载体pcDNA3-IKKβ。将重组载体转染入HEK293细胞中,并通过免疫印迹方法检测IKKβ的表达。结果酶切及测序结果显示,重组质粒构建成功;免疫印迹结果显示,瞬时转染重组质粒的人胚肾细胞HEK293中可有效表达IKKβ。结论本研究成功构建了IKKβ真核表达载体,并能够在真核细胞中进行表达,为进一步研究IKKβ的生物学功能奠定了基础。
Testis-specific protease 50(TSP50) has been identified as a testis-specific protein that is expressed abnormally in most human breast cancer samples,which makes it an attractive molecular marker and a potential target for diagnosis and therapy.In the present study,we prepared a panel of monoclonal antibodies(mAbs) with high specificity and sensitivity against TSP50 by hybridoma method and characterized them by ELISA,Western blot,immunofluroescence and immunohistochemical analyses.The results show that all of the 9 different clones can specifically bind to TSP50.The mAbs against TSP50 we generated could be good tools for both basic and clinical studies.
