    I have some whole Rat bone (femur) specimens that I expect to be
expressing GFP.  I want to look for GFP in transverse (circular)
cross-sections of the femur.  A colleague had suggested that I use Spurr's
Resin to embed the entire bone and then image the cross-sections using
confocal.  This sounds like a great idea to me, however, since GFP is
quickly degraded with alcohol there are major hurdles to overcome.

I am faced with the following questions regarding these tissues:   After
fixing the femurs in 4% paraformaldehyde, what non-alcohol solution should
I store them in until I embed them?  In the protocol for embedding in
Spurr's I obviously need to dehydrate the tissues;  how does one do that
without alcohol?  Is there a different method someone might know of to
image transverse cross-sections of femur and still be able to image GFP

Thanks in advance for your assistance!
