今天进行了GST融合蛋白的表达，pGEX-4T-1载体,BL21菌。 步骤：摇菌至A600：0.7，然后加IPTG诱导3小时，温度35度（终浓度：0.3mM)，取1ml诱导后菌，离心去培养基，冰冷PBS洗一次，离心，吸净液体，加入1*上样缓冲液50微升和终浓度1mM PMSF，100度煮菌5分钟，离心，取20微升上清跑胶。结果如图。 1.空载体对照有GST的表达 2.所有重组载体同样有GST大小的片断，（箭头 B） 3.箭头A所示的条带在空载体和重组载体处有明显差异。 4.我的目的
！希望大家多讨论一下给我点经验和建议，谢谢大家啦！ kinguangjun 你好！要增加可溶性，可以换成为能增加可溶性表达的载体来试试，例如pGEX-4T-1或pET32a(+)等，如果还是不行，可能只能用真核表达系统啦！ woxingwosu kinguangjun wrote: 你好！要增加可溶性，可以换成为能增加可溶性表达的载体来试试，例如pGEX-4T-1或pET
