Biological Staining Fast Blue BB Salt CAS 5486-84-0

Fast Blue BB Salt hemi(zinc chloride) salt, also known as Cl Azoic diazo 20 (Cl 37175) is a diazonium salt that possesses a lipophilic amine lipophilic with an aromatic system of moderate size. It is commercially available as the zinc chloride double salt.

Fast Blue BB Salt hemi(zinc chloride) salt has been used for alkaline phosphatase staining in cells.

Fast blue BB salt is suitable for the staining of enterochromaffin. Its applications are seen in enzyme histochemistry by Gomori and are suitable for the histochemical demonstration of beta-glucuronidase activities, and various peptidases and proteases. It is also used in enzyme histochemistry including the demonstration of serine esterase in blood smears and histological sections. Fast blue BB salt plays a vital role as a routine stain to demonstrate alkaline phosphatase labeled antibodies.
