问 一个lentivirus的问题# Biology - 生物学

3月4号电话面完(Skype video)。4月21号接到校园面试通知。5月1号面试。需
要准备1小时研究报告(RESEARCH SEMINAR)。没提教书。显准备P
PT中。有一下问题需大牛相告:
1。PPT 格式清新点(比如空白)还是花哨点(有图案)。
2。能出现现在单位的LOGO吗?
3。要用面试学校的LOGO吗?(只是首页,还是每页都要?)
4。感谢页是第二页还是最后一页。
5。大约多少页比较合适(1小时,估计10-15分钟提问)。

I am testing transduction of lentivirus (vsv-g) in primary hippocampal
neurons.
I have tried 5ug/ml polybrene for over night, however I have observed
tremendous cell death. : ( Any suggestion for a better way to infect primary
neurons?
Thanks ahead!

看个人风格,不过我个人偏向于清新点,总之我的原则是如果你不准备讲某个图或者表
,那么最好就不要放在ppt里
可以的
好像比较少见
最后一页,尤其是如果你有合作,放在最后一页比较方便说刚才讲过的某某工作是跟某
某合作的
30-40页,我老板跟我说提问环节更能体现一个人的水平,所以一定要留足够多时间给
听众提问。

有对照吗?
尝试降低vsvg包膜蛋白质粒在转染时的配比,vsvg的毒性对很多细胞比较强。另外就是
尽量提高包装效率,用尽量少的病毒上清感染

The virus I used is high efficient, it has been tested previously by other
labs on multiple cell lines and stem cells, but not primary rat neuronal
culture. I had a control with polybrene alone, it was toxic. I also
increased the quantity of virus I used, which helped a little bit. The only
thing I haven't tried is to adjust the ratio between virus and polybrene. So
frustrated.....
PS: love your profile photo : )

Polybrene warns not to used on primary neurons. Do spin transduction maybe?

what is spin transduction? SORRY, I AM SO DUMB.

maybe?

如果是这种情况,那自然没啥好说的,降低polybrene的比例甚至完全不加,很多情况
下一样可以感染只是效率降低,我对primary neuro cell不熟,但是在primary
hepatocyte上,spin infection效果还不错

You don't have to use polybrene for lentivirus transduction in primary
neuronal culture. If you concentrate the lentivirus, make sure to spin down
the undissolved pellet after re-suspending the viral particle. The
undissolved pellet could be toxic for cells too.

Do you mean that I should add the virus directly?

很简单,就是染毒后细胞培养板在2000rpm(800g?)32度/37度下离心1-2小时,具体
的条件参数根据不用的细胞可能需要调整

with polybrene? or without? I checked some websites, most people still use
polybrene. Do you use it in your case? I guess 1 or 2 hrs incubation of
polybrene is not as toxic as overnight?

without,因为之后并不换液啊。对你的情况先尝试不加polybrene吧,效率可能会降低
,但因为毒性问题也不得不这么尝试一下,没准运气好。假如效率显著降低没法用,就
再试试spin infection with polybrene,然后孵育4-6小时再换液,这样比过夜强点

Thanks SO MUCH. You have been very helpful. Good luck with your experiments/
career. I will update you later. : )

That's what I normally do with primary neuronal cells (10 MOI).
