6-Chloro-3-indoxyl-beta-D-galactopyranoside 6-氯-3-吲哚-β-D-吡喃半乳糖苷  

貨號：C-5000  

CAS號：138182-21-5

Chromogenic substrate for beta;-galactosidase yielding a salmon colored precipitate. 6-Chloro-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) for the detection of beta-galactosidase activity in bacterial colonies, in a colorimetric assay to detect recombinants (white) from non-recombinants (salmon). In conjunction with X-Glc, Salmon-Gal is useful for simultaneous detection of GUS and Lac activities on the same plate.
