质粒简介
The use of pAdVAntage vectors were transfected into mammalian cells can promote the initiation of translation to enhance the instantaneous protein expression in many cell types.
Transfection of mammalian cells with expression vector often leads to the expression of the target protein. The double stranded RNA (dsRNA), which is produced in the transfection process, is thought to activate the dsRNA- activation inhibitor (DAI), which is one of the many kinds of enzymes involved in the host cell antiviral defense system. DAI phosphorylation of translation initiation factor eIF-2, termination of translation and generation of protein. However, with the pAdVAntage vector were transfected into DAI in the process of translation inhibition by RNA polymerase III generated adeno-associated virus type I (RNA VAI RNA) offset. RNA DAI combined with VAI to prevent its activation, so as to complete the translation and protein expression.
质粒图谱
pAdVAntage哺乳辅助质粒使用说明:
1、收到质粒干粉后请先5000rpm离心1min,再加入20μl无菌水溶解质粒,室温放置1min;
2、从-80℃冰箱中取出相应的感受态,置于冰盒上解冻,并做好标记;
3、取2μl质粒加至100μl感受态中,冰浴30min;
4、42℃热激90s,再冰浴2min;
5、加入900μl无抗的LB液体培养基,180rpm震荡培养45min;
6、6000rpm离心5min,仅留100ul上清混匀菌体沉淀;
7、混匀后的菌液加至对应抗性的LB平板上,倒入适量玻璃珠,涂匀液体;
8、将平板正向培养1h,再倒置培养12h~16h;
9、挑取单克隆菌落至对应抗性的LB液体培养基中,震荡培养12h~16h,根据实验需要提取质粒。
pAdVAntage哺乳辅助质粒注意事项:
1、如果您收到的是甘油菌种,请先四区划线,挑取单克隆培养。
2、如果第二天转化平板长的过多,请将质粒按比例稀释后再转化。
