摘要
[目的]构建牛整合素β5亚基(ITGB5)基因,并进行原核表达。[方法]扩增目的基因,将其重组到pET-32a(+)质粒中,将经鉴定为阳性的重组克隆,转化大肠杆菌感受态细胞表达蛋白后纯化。[结果]从牛甲状腺、扁桃体扩增到目的基因ITGB5;ITGB5基因表达产物的SDS-PAGE结果显示,在88 KD处出现表达产物及纯化后的蛋白;W estern-blot分析表明,抗血清可与原核表达的蛋白特异性结合。[结论]表达、并纯化了ITGB5蛋白。
[Objective] To clone and express integrin beta 5 subunit(ITGB5)gene of bos tauros.[Method]Objective gene was obtained,and cloned into pET-32a(+) vector.The recombinant plasmid was transformed into E.coli BL21 to express,then the expected protein was purified.[Result] ITGB5 gene was obtained from thyroid and tonsils of bos tauros.An about 88 KD expected protein was determined by SDS-PAGE.And the result of Western-blot showed that the expected protein could be combined by specific antibody.[Conclusion]The ITGB5 protein was expressed and purified.
