Greetings I recall that years ago Biomeda had a product called Stable DAB. It was a ready-to-use product that was stored in the freezer. Does anyone know if it is still being produced and whom I should contact? William (Bill) O'Donnell, HT (ASCP) QIHC Lead Histologist Good Samaritan Hospital 10 East 31st Street Kearney, NE 68847
