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 doubt very much that you will be dealing with EDTA but with formic acid decalcification. People who have developed acid decalcifying solutions, with either formic acid or hydrochloric acid tout that the bone section looks very good, better that if EDTA is not present in the solution. I never tested this claim in our bone studies, but it might be something to try, an acid solution containing EDTA and one without EDTA (keeping the same kind of acid in the study). The acid is going to ionize the calcium from bone at a faster rate than the EDTA can chelate the calcium. But most importantly, EDTA does not work in a low pH environment. The chemistry of how EDTA acts at different pHs is well documented by chemists, and found in book chapters on EDTA. My physical chemist spouse supplied me with such a chapter. The pH of formic acid is what, pH 3 or so, and if so, EDTA only begins to chelate calcium around pH 4, and when fully protonated at pH 8, decalcifies faster at that pH than at pH 4, or below pH7. The working pH for most EDTA solutions is commonly 7 to 7.6, but when the pH becomes more alkaline ( and 8 is going into alkaline range) then alkaline sensitive protein linkages can be damaged. EDTA, correctly written out by Rene Buesa e.g. ethylene diaminatetraacetiic acid comes in several molecular weights depending on whether is it EDTA without attached sodium, EDTA disodium and EDTA tetrasodium. Tetrasodium is very soluble in water or PBS, but has a very alkaline pH that requires adjustment down to pH 7 to 7.6 or that high pH will damage alkaline sensitive protein linkages. EDTA and disodium EDTA are not as soluble, usually no more than a 10% solution, requiring heat or addition of sodium hydroxide in order to dissolve. EDTA is also expensive, not affected by heat up to 60C but only if the bone is totally fixed with NBF. I would not advise using 60C during lengthy EDTA decalcification, and possible damage to heat labile antigens. There are publications on using EDTA to decalcify fresh bone samples, then snap freeze, cut frozen sections, then acetone fix the sections for murine CD markers compromised by both NBF and acid decalcification. EDTA mixtures are found in Histonet Archives, histotechnology books and on websites e.g. IHCworld, as a chelating agent, it is a very slow decalcifier. More advantages of EDTA are - no damage to antigens, nucleic acid staining, nor other tissue components. It does affect the enzyme histochemical stain for alkaline phosphatase, and magnesium ions (chelated by EDTA) must be replaced in the staining solution. Most clinical laboratories prefer to use formic acid or hydrochloric acid decalcifying solutions instead of EDTA when rapid diagnosis is needed. If you try EDTA alone, rinse the bone well (after decalcification) with running tap water since residual, excess EDTA in tissue precipitates in presence of alcohol, and the ppt makes the tissue difficult to section. Endpoint determinations for complete removal of calcium with EDTA cannot be done chemically, although there is a weight gain/weight loss method that we use routinely that works or use an Xray machine, Faxitron. You can buy EDTA mixtures from Poly Scientific and some other suppliers, or make it up yourself. Otherwise, try the formic acid with EDTA, it may work very well for you while not sacrificing speed for diagnosis. Formic acid will be less damaging to antigens than hydrochloric acid, and is a popular decalcifier because it is gentler than HCl. Good luck Gayle M.

Formic acid demineralization will work fine, the theory of using EDTA with it makes no sense. EDTA demineralization usually uses the disodium salt. EDTA by itself is not very soluble but its sodium salts are. It can be present as mono-, di-, tri- or tetra-sodium salts depending on the pH. At pH around 11 there are 4 groups that can be replaced with for example calcium. Usually the disodium salt of EDTA is used as the tri and tetrasodium salts are only present in very alkaline solutions that tend to cause tissue maceration. At acidic pH the EDTA will only work slowly and have one group replaceable as the monosodium EDTA. There are several good formulae for using EDTA and formic acid in separate formulae, depending on your specific needs..

This is a recipe from a Dr. Webster (Webb) S. S. Jee publication. We like this since this 14% EDTA dissolves immediately in water or PBS compared disodium EDTA, and at a higher concentration = more molecules of EDTA available. We are very careful to NOT use this 14% tetrasodium EDTA at it original pH of around 10 or more. Decalcification is still very slow, but a recent bone project required EDTA decalcification (so we thought!) to protect antigens never stained before in our lab. After trying both the EDTA and 10% formic acid, we found the antigen to be very robust after formic acid decalcification too. Lesson learned, don't put off a pilot study to test IHC after acid decalcification. The formic acid would have been faster and cheaper.
