Abstract
Gentle sulfation of formalin-fixed tissue sections followed by staining in a hematoxylin-azure B sequence results in bright blue staining of tissue elements that stain with the periodic acid-Schiff reaction—especially basement membranes. The stain is relatively rapid, simple, and permanent, is performed with inexpensive, readily available laboratory reagents, and is presented asan alternative to periodic acid-Schiff staining.
