We do lots of mouse work, I fix in 10%NBF for 24 hours the samples are
cut in to get maximal fixation.

Hi all!

We have a researcher here who is submitting normal whole mouse
organs
(liver, heart, lung, kidney) for paraffin processing for use as IHC
controls.  Currently, she is fixing these organs in 10%NBF for 4
hours to
retain as much immunogenicity as possible, however, I am worried that
the
organs are not completely fixing and are drying out in the alcohols. 


What fixation procedures do those of you who work with mouse tissue
use?
How long in fix when doing IHC?  Are the organs grossed open prior
to
fixation or left whole?

Thanks for any help!
