用于ihf的p4小鼠大脑需要先pfa perfusion么,还是直接挖出来扔pfa过夜就可以了?
老板说不用,有人说用生理盐水perfusion就可以了,到底怎么样比较好呢?

对的,目的就是为了去掉肺部的所有血细胞,结束以后肺应该是纯白色,为进一步分离
原代细胞做准备。测流感病毒titer可以不做perfuse。lysis buffer是专门裂解已经分
离好样品中污染的RBC的。希望这些信息会有帮助。

这个问题我真的懒得多说了。不过还是忍不住多两句嘴。
理科同学:请去查查cast iron的熔点,再去查查steel的熔点。知道为什么中式炼钢大
多从cast iron开始吗?因为cast iron熔点最低!因为炉子温度不够!所以只能得到
cast iron!
在早期炉温不够的条件下,西方的smelting方法直接得到wrought iron,质量比cast
iron转化过来的钢高很多,缺点是产量低、价格贵。中式perfusing steel质量低,优
点是产量高、价格便宜。对于民用农具之类,便宜量大的perfusing steel有优势;对
于兵器,只要质量高,再贵也是wrought iron好。
以上都是历史上确凿无疑的facts,不要再争辩了。谢谢!
我前面也说了:在不同市场上,只有最对,没有最好。民用钢就是便宜为王、军用钢就
是韧性为王。硬要撇开用途分个高下、甚至眼睛一闭不承认事实,是脑筋闭塞、不开化
的表现!!

the radiologist and cardiologist? at least the cardiologist didn't sound

gold standard? did she have any cardiac perfusion study done? there are a

来自主题: Biology版 - 关于IHC tissue preparation的求助
I was under the impression that perfusion is mainly to get rid of the blood
or more specifically IgGs out of the tissue so there will be much less
background in IHC.
Correct me if I am wrong
For embryos, endogenous IgGs are relatively low compared to adult tissues.
Maybe that's why it works well without perfusion.

我也来搭个车来说说自己关于不同条件的fix下的对于IHC的影响。
我是做眼睛的, 我做过如下的比较,
1. Whole globe: O/N fix in 4% PFA
2. Whole globe: 1hour RT in 4% PFA
3. Slit the cornea (more access to PFA) : O/N in 4% PFA
4. Slit the cornea: 1hour RT in 4% PFA
I compared immunogenicity of CD31 and PDGFRb.
Results were:
1>=4>2=3
As for the brain, I usually perfuse and fix with 4% PFA and post-fix in 4%
PFA O/N.
Today I didn't perfuse, I guess I may just leave the brains in 4% PFA for
36hours.
