[Histonet] EDTA

EDTA (which stands for Ethylene-diamino-tratacetic-acid) is a chelating agent and the method of choice to decalcify BM biopsies.
The thing is that it should be used alone, and not combined with any acid, as you state (not even formic acid).
By itself will produce an extremely gentle decalcification that will be completely suitable for IHC studies.

I am looking into the various decals on the market and have found one that in addition to formic acid, has EDTA in the mix.  I have never worked with EDTA so would appre ciate any help in your comments on the use of EDTA in decalcification methods for bone marrow and routine specimens.

Thank you ahead of time for your advice!
