[Histonet] Bone marrow enzyme stains

[Erin Wrona]

Hi All,
   
  About two years ago we were told that our supplier would no longer be manufacturing the kit for beta-Naphthyl Butyrate Esterase Lymphocyte. We started using Alpha-Naphthyl Acetate Esterase with and without flouride as a "temporary back up".  Our bone marrow pathologists would like to go back to the beta.  Does anyone know of a supplier, or something comparable?  What do you use in your facility?
   
  Thanks so much,
