Beschreibung

Chromogenic substrate for beta-D-galactosidase yielding a lapis colored precipitate. 5-Bromo-3-indoxyl-beta-D-galactopyranoside can be used in conjunction with Isopropyl-beta-D-thiogalacto-pyranoside as an alternative to 5-bromo-4-chloro-3-indolyl beta-D-galactopyranoside (X-gal), producing a darker blue color for detection of beta-galactosidase activity in bacterial colonies in a colorimetric assay to detect recombinants (white) from non-recombinants (blue). 5-Bromo-3-indoxyl-beta-D-galactopyranoside is also used in histochemistry to demonstrate beta-galactosidase activity in tissues.
