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.

Use of the rapid diazonium blue B test to differentiate clinically important species of Trichosporon and Geotrichum.

D L Oblack et al.

Sabouraudia, 21(3), 243-245 (1983-09-01)

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

Investigations into the cellular contribution to host tissue proteases and inhibitors in gingival crevicular fluid.

C N Kennett et al.

Journal of clinical periodontology, 24(6), 424-431 (1997-06-01)

Gingival crevicular fluid (GCF) was collected from chronic periodontitis patients using plastic micropipettes and coverslip smears stained with antibodies for leukocyte markers and Toluidine Blue for mast cells. The smears consisted of 70-80% granulocytes, 10-20% monocytes/macrophages, 5% mast cells and

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
