Problems with extraction of RNA from primary culture - (Jan/15/2013 )

Hi there,

I am working with mixed glial/neuronal primary culture (P1&P2) from cortex. I am having some problems with the extraction of RNA.
From 2 X 10^6 cells per well I can't get more than 70ng/ul. I have used kits like Qiagen, Roche, and TRIZOL.

Does anybody have any suggestion?

Thanks

Are you aware that neuronal tissue has high lipid content? Did you use specific kits or modifications for this kind of tissue?

(By the way, DON'T post multiple identical topics into several subforums)

Hi,

Thanks for replying. I have used specific kits for cell:
Qiagen mini kit
Roche high pure RNA tissue kit
TRIZOL, following a protocol from other colleagues that are used to work with primary cultures and cell cultures in general

There is a special Qiagen kit for lipid tissues RNeasy Lipid Tissue kit, but Trizol isolation protocol should be suitable even for those.

Hi,

I haven't tried that one. The last one that I have used is ReliaPrep RNA Cell 20Miniprep - Promega. This one works really well.

Cheers
