请教一下现在是不是有些卖的plasmid只能用一次# Biology - 生物学s*l2010-02-28 08:021 楼今天跟一个生物系朋友聊天,听说现在有些卖质粒的公司有技术可以让他们的质粒只能被用一次,以后还要用就要再买,不知道这里的大虾有没有了解的?大概原理是什么,是哪个无良公司先搞出来的?谢谢
a*d2010-02-28 08:023 楼maybe they are talking about packaging plasmids mix, or something like that.But still, you can figure it out. But if you have to use specific enzymesfor the reaction, like the pENTR system from invitrogen, then you have topay for the reagents.
