摘要 为建立一套适合叶用莴苣(Lactuca sativeL.)热激蛋白研究的SDS-PAGE和Western-blot方法。以叶用莴苣W7为材料,采用改进的TCA/Acetone法提取叶片蛋白,比较了2种电压下SDS凝胶分离蛋白质的效果,使用4℃保存2周的抗体稀释液,并且得到了较清晰的热激蛋白70和内参蛋白Rubisco条带,初步确定了叶用莴苣叶片热激蛋白的western-blot实验条件。 In order to establish a method SDS-PAGE and Western-blot suitable for heat shock protein study of Lactuca sative L.,with leaves of Lactuca sative L.(W7) as material,the author used improved TCA/Acetone method extracted leaf protein,compared protein separating effect in SDS gel in two different volt,obtained clear bands of HSP70 and rubisco using anti-body diluent stored 2 weeks at 4℃,optimized and preliminary established Western-blot experiment condition of heat shock protein of Lactuca sative L.young leaves.
