Thermo Scientific Chemicals Echtblausalz BB
Beschreibung
Fast Blue BB salt is used as a general substrate for β-glycosidase. Two moles of 6-bromo-2-napthol-β-d-glucopyranoside are cleaved by β-glucosidases into 2 moles of d-glucose and 2 moles of 6-bromo-2-napthol. The 2 moles of 6-bromo-2-napthol formed are coupled with 1 mole of Fast Blue BB salt [4-benzoylamino-2,5-diethoxybenzenediazonium chloride hemi (zinc chloride) salt], resulting in 2 moles of the corresponding dye of 6-bromo-2-naphthol (reddish color). It is a commonly used stain to observe myelin under light microscopy.

Echtblausalz BB wird als allgemeines Substrat für β-Glykosidase verwendet. Zwei Mol 6-Bromo-2 -napthol-β-d-Glucopyranosid werden durch β-Glucosidasen in 2 Mol d-Glucose und 2 Mol 6-Bromo-2-Napthol gespalten. Die gebildeten 2 Mol 6-Bromo-2-Napthol werden mit 1 Mol Echtblausalz BB [4-Benzoylamino-2,5-Diehoxybenzendiazonium-Chlorid-Hemi(Zinkchlorid)Salz] gekoppelt, was 2 Mol des entsprechenden Farbstoffs 6-Bromo-2-Naphthol (rötliche Farbe) ergibt. Es ist ein häufig verwendetes Färbemittel zur Beobachtung von Myelin unter Lichtmikroskopie.
