Application

  • Fast Blue B has been used in the acid phosphatase test in Clostridium perfringens.
  • It has been used as a spraying agent in thin layer chromatography for the identification of separated components.
  • It has also been used for the determination of the lipase activity.

Biochem/physiol Actions

Fast blue B is used for the determination of acetylcholinesterase activity. Acetylcholinesterase converts 1-naphthyl acetate to 1-naphthol, which reacts with fast blue B to form a purple-coloured diazonium dye. Similarly, fast blue B is also used for α- and β-glucosidase activity.
