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.

In this study, composite anion exchange membranes (AEMs) were synthesized by cross-linking poly(phenylene oxide) (PPO) with cellulose functionalized by 1,4-diazabicyclo[2.2.2]-octane (DABCO) or di-guanidine (DG). The structural and morphological characteristics of the synthesized AEMs were characterized by FTIR, 1H-NMR, SEM, TEM

Trichosporon isolates form pink to violet pigments following reaction with diazonium blue B which reliably differentiates them from Geotrichum species. The inoculum could be grown in static culture without diminishing the colour intensity. This modification facilitates use of the diazonium
