然后你得确定,这个细胞株对于你得研究来说不可或缺,具有明确的代表性。
上面两个都没有问题的话,祝你顺利。
① 在构建载体时,目的基因直接整合到细胞染色体组上,最好不要通过先瞬转在筛选稳定细胞株的这种方法,因为转染效率没有保证
② 高表达载体的构建,哺乳动物表达量一直是它自身的缺点,最好根据高表达载体定向的驯化细胞,提高蛋白表达量
③ 细胞的选择,筛选稳定细胞株我们常用的细胞是CHO,中国仓鼠卵巢细胞,由于CHO具有诸多的优点因此适合用于筛选稳定细胞株,而HEK293细胞则常用于瞬时转染
④ 后期的筛选,双抗预防污染,筛选细胞的时候抗生素浓度一定要做预实验,而且转染的时候不能有抗生素,关于细胞转染 稳定细胞系构建的相关理论
如果经费充足的话可以找公司包装病毒,如武汉的普健可以提供各种载体的构建及细胞株构建的技术服务。
