鸡细胞周期蛋白依赖性激酶抑制蛋白p21单克隆抗体的制备
Generation of monoclonal antibody against chicken cyclin-dependent kinase inhibitor p21
摘要
Abstract
To prepare monoclonal antibody against chicken p21,the p21 gene was amplified by reverse transcription polymerase chain reaction(RT-PCR) and subcloned into the prokaryotic expression vector,pET-30a.Therecombinant plasmid,designated as pET-30a-p21,was transformed into E.coli BL21(DE3)competent cells.Separated by SDS-PAGE,the induced protein was shown to be expressed as inc]usionbodies.The positive bands were cut,ground and used as antigens to innunize BALB/c mice intraperitoneally for three times.The spleen was isolated and fused with SP2/0.Hybridoma clones that produced antibodies against p21 were screened by IFA,ELISA and limited dilution.The antibody levels were detected by indirect immunofluorescence assay (IFA),enzyme-linked immunosorbent assay (ELISA) and Western-blot.Twelve positive hybridoma clones were screened and identified as 1B12,1E12,1H7,2B5,2C5,C8,2D8,2F2,3C11,3D6,G7 and 4G6.The monoclonal antibody against p21 was prepared as a tool for the study of p21 functions.关键词
