因为喜欢AD/PD而选择了neuroscience,可是没有走成。
现在是retinal research,越研究越觉得有意思。
但是AD/PD是心中挥不去的遗憾。

我的建议是,在和老板争论是否有deletion之前,利用其他的办法证实你的PCR所发现
的结果。PCR是很容易出错的,如果你能利用Southern证实homozygous的deletion确实
存在,相信你的老板是会接受你的结论的。
Constance L. Cepko实验室最近retract了G&D上的一篇文章,很好的说明了PCR的易错
性。有兴趣的可以看看。

来自主题: Biology版 - lentivirus实验请教
What are lentiviral vectors?
Lentiviral vectors are a type of retrovirus that can infect both
dividing and nondividing cells because their preintegration complex (virus
“shell”) can get through the intact membrane of the nucleus of the target
cell. Lentiviruses can be used to provide highly effective gene therapy as
lentiviruses can change the expression of their target cell's gene for up to
six months. They can be used for nondividing or terminally differentiated
cells such as neurons, ma... 阅读全帖

retina has three vascular layer, one is the most superficial layer where
lies the veins and arteries,the second is the superficial capillary bed and
the deepest is called the deep capillary bed.

thanks for your advice, andy.
I don't know how to culture the primary cells.
and I want establish some rho-zero cells (delete the mtDNA)
and I need long time incubation the cell with EB.
so how many passages usual the primary RGC survive?

Although I work on retinas, I do not focus on ganglion cells even though my
research involves a bit of glaucoma.
So I cannot provide more information rather than a suggestion.
You may look up some people in this field and see how it works.
Good luck.

视网膜里的感光细胞有两种,一种是视杆细胞(rod),一种是视锥细胞 (cone)。Rod
可以感受一个到几个的光子,所以灵敏度很高,一般用于dim vision,而cone则需要比
较高强度的光来刺激,一般用于白天等比较亮的情况下,决定visual acuity。
在大部分的生物里,rod和cone是平行分布的,但是这篇文章研究了彼式象鼻鱼(
Gnathonemus petersii),一种生活在浑浊环境里的鱼。很早之前就有人发现了他们的
视网膜结构是比较另类的,既不是dim下用rod,bright下用cone,他们视网膜结构属于
