有过老鼠的房子还能买么?哪位有这方面的经验分享一下!

D*****l 发帖数: 554 | 13 我最近得到knockout mice.一个可能是癌抑制基因,被我成功knockout.小鼠有三个月

|
O******e 发帖数: 4845 | 14 如果我是你,第一要做的,就是确定这个5% p53 expression。
你得非常肯定这个变化是真的,否则可能是瞎忙活。
第二要做的,比较快的,give them some DNA damage or other tumorigenic
drugs/chemicals,然后观察肿瘤发生的变化。
如果你那个5%的表达量是真的,什么都不做,你的KO Mice也会自然产生肿瘤并很快死
掉。 |

p*********e 发帖数: 23 | 22 也有这种情况
但楼主说“是利用在其两个exons之间插入另一个不相关的gene,来使其原蛋白丧失功
能”
所以严重怀疑是个genetrap knockout
后来楼主又提到“此KO mice体内有好几种此蛋白的变异体(由不同的exons变换组合而
成)”
我想这是指alternative splicing
一般用同源重组做KO时,可以在设计时避免alternative splicing的干扰。 |

I have something in my mind before I want to start it.
If a gene of interest is known critical for embryonic development, is it
really important to bypass the embryonic stage and look at the phenotypes of
loss of function after the mice are fully developed? I think so, but it
