Thermo Scientific Chemicals Sal Fast Blue BB
Descripción
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.

Se escinden dos moles de 6-bromo-2-naftol-β-d-glucopiranósido son escindida mediante β-glucosidasas en 2 moles d-glucosa y 2 moles de 6-bromo-2-naftol. Los 2 moles de 6-bromo-2-nafthol formados se combinan con 1 mol de sal Fast Blue BB [sal de 4-benzoylamino-2,5-dietoxibenzendiazonium cloruro hemi (cloruro de zinc)], resultando en 2 moles del colorante correspondiente de 6-bromo-2-naftol (color rojizo). Es una tinción comúnmente usada para observar la mielina bajo microscopía óptica.
