We are using Sigma's Chloroacetate Esterase kit, and are doing one on a B5
fixed bone marrow slide. Our problem is thus: Both myself and the stains
tech recall in the recesses of our collective memories, that Na thio/iodine
to remove the mercury pigment produces a false negative for this test.
Is there anyone else out there that confirms or contradicts this?? We are
reluctant to proceed and possibly ruin a slide, as well, we do not want to
stain it, and leave a bunch of mercury which may impair diagnosis.
Your help is greatly appreciated!
