Re: cold decalc

I suspect you are right Joey, if your samples spend too long in fixative 
it will be difficult to retrieve immunoreactivity after decalcification. 
With mouse bones we restrict paraformaldehyde fixation to 48hours and then 
decalcify. We have recently discovered Immunocal decalcifier which gives rapid decalcification and enables subsequent 
immunocytochemistry to be carried out. The supplier of Immunocal in Europe

Hi everyone
Does anyone else out there use EDTA decalcifcation at 4'C? Its been 
reccomended to me for good IHC results. If so what strength/recipe do 
you use and how long does it take? I'm currently using a 20% EDTA 
solution at room temperature on mouse hind limbs - it seems to take 
forever and my antigen retrieval for IHC is pretty bad (although I 
strongly suspect that's due to very long periods spent floating in 
formalin - many of these are archived samples!).
Thanks,

Joey
