RE: skull decalcification

From:Cynthia Favara


I have done fixed sucrose protected frozen sections and paraffin embedded
sections on neonatal mice up to 2 weeks of age without decalcification. I
have used a few strains of mice and found the skull cap to be thin enough to
section with little or no difficulty. I found careful dissection after
fixation to remove the lower jaw is necessary.  

As usual Gayle gave a good protocol for decalcification if necessary.

Subject: skull decalcification

Hi everyone.  Does anyone have a good way to decalcify mouse skulls that
doesn't shrink or otherwise alter the brain?  We want to section mouse
heads from neonates through 2 weeks of age.  I know that we'll have to
change the time that the brain is in the decalcifying solution,
depending on the age of the mouse, but if anyone can recommend a good
decalcifying solution or give any other advice, I'd really appreciate
Thank you.
