If the antigen is not damaged by acids, then buffered formic acid should
work using endpoint determination to ensure no overexposure to the acid.
Normally we do 14% tetrasodium EDTA in Dulbeccos PBS at pH 7.4 - 7.6, the pH
range of TRIS buffered saline. WE do adjust the pH down with glacial acetic
acid using constant stirring and a pH meter. The decalcification may take a
week or more, once again tested with endpoint determination, the weight
gain/weight loss method or FAXITRON xray method.
Mouse paws take longer to fix with NBF than you think, unless you start with
perfusion fixation followed by immersion. We have fixed for up to a week
since the bones are very packed very closed together with skin and tendons
