标题Re: [问题] DNA ladder实验
时间Sun Jan 27 01:30:25 2008
想请问一下为什麽有些DNA ladder的实验结果中,
有的ladder会很乾净,如
图1:

但是有的在各个梯型条带中有smear的感觉
例如上图的B,或者

是因为有一点necrosis吗?还是抽DNA或跑胶没跑好?
我最近在做DNA laddering的实验,结果就像第二、三张图,
测OD的结果260/280值大多是1.9几,不晓得到底要如何改进呢?
还是说细胞本来就正在apoptosis+necrosis呢?
先谢谢各位的回覆罗!

1F:推 K587262:有点late apoptosis, 时间点稍微往前一点抓吧 01/28 11:38
