Hey there.  I *personally* haven't done any RNA work for LCM on
pancreatic tissue, but I have listened to two (independent) researchers
- who work on mouse pancreas - rave about how RNAlater (Ambion) saved
their sanity.  Another researcher really liked the LCM staining kit
(also from Ambion) b/c it prevented the activation of endogenous
proteases through the use of non-aqueous solutions.  Again, I haven't
used these techniques, but I've heard how difficult the pancreas can be
to deal with and I thought I would pass these on as a possibility.

Good luck,

Jacqui

Subject: [Histonet] Pancreas RNA

Hello:
Does anyone have experience working with pancreas tissue for downstream
LCM?  Particularly FFPE and frozen collection procedures/protocols.  We
have tried both formats, and were unsuccessful in maintaining RNA
integrity.  We've tried to get around the endogenous ribonuclease issue
by snap freezing in chilled isopentane, or a direct fixation in 10% NBF.
Any help is greatly appreciated.
Madeline
