If we do not use fresh tissue for RNA preps we store it prior to prepping
at -70 C and never thaw it in between. I have the option to use tissue of
interest that, however, had been stored at -20 C. Does anyone have
experience concerning the state of the RNA extracted from such a source?
I remember vaguely that a similar question was posted before but I did not
see the outcome.
Thanks in advance
