[Histonet] rat femur histopath

[Gayle Callis]

Missy,

Any acid decalcifier should work fine, we use 10% formic acid but you need 
to do endpoint determinations to make sure the bone and soft tissues are 
not ruined by the effects of overexposure to acid aka 
overdecalcification.   Rinse the bones for a few hours, process longer into 
paraffin unless you are bisecting the femurs.  We did our rat femurs for 2 
hours per station on a VIP, and use Tissue Prep 2, a harder paraffin that 
is better for sectioning for rat femurs and whole rat knees.

I have a quick weight loss/weight gain endpoint determination that works 
well if you do not have a FAXITRON to xray for endpoint, or do not want to 
do a chemical endpoint test - you can do that too.
