Hello!
I am planning isolation of RNA for the next days, RT reactions afterwards, and a lot of PCR and real time PCR.
These will be done within as short period as technically possible.
The problem is that here we have only -20 deg and liquid nitrogen.
I don`t really trust the freezer.
Can I store both RNA and cDNA samples in liquid nitrogen?
Will this affect my PCR results?

please help

thanks
