| 摘 要： | 通过PCR扩增出集胞藻6803 C-PC编码基因cpcA,构建表达质粒pET32a(+)-cpcA,转化大肠菌株BL21(DE3)pLysS,用IPTG诱导表达、经His-tag纯化后免疫日本大耳白兔获得多克隆抗体。间接ELISA法揭示该抗体效价可高达1∶1 025 000;蛋白免疫印迹确定该抗体具有高度特异性。应用该抗体进行蛋白免疫印迹检测,结果发现C-PC蛋白在生长光与高光培养条件下的数量,以及与2个光系统间的连结数量均存在显著差异,为进一步研究藻胆体的杆在响应与适应机制中所承担的重要角色奠定了生化基础。

| Abstract: | In this study,the encoding gene,cpcA,was PCR amplified from the unicellular cyanobacterium Synechocystis sp.strain PCC 6803,the expression plasmid pET32a(+)-cpcA was constructed and transformed into BL21(DE3)pLysS,and the expression of C-PC protein was induced by IPTG.After purification,the fusion protein His-C-PC was used to immunize Japanese white rabbit to obtain the polyclonal antibody.The titer of the polyclonal antibody was detected by ELISA and its specificity was analyzed by immunoblotting.The resul... |
