Formule :C20H26BrClN2O7Degré de pureté :Min. 99 Area-%Masse moléculaire :521.80 g/molBCM® Histamine-producing bacteria Broth
Growth medium for the detection of histamine-producing bacteria in food and water samples. The medium contains an indicator that turns orange/red (absorbance at 555 nm) due to metabolites released by histidine decarboxylase. The BCM® Histamine-producing bacteria Broth contains tryptone (FT09555) and yeast extract, together with the chromogenic agent. High-level histamine-producing bacteria yield orange to red coloration in less than 2 days and even after 24 hours, while cultures of other bacteria remain yellow.Degré de pureté :Min. 95%6-Chloro-3-indoxyl-beta-D-galactopyranoside, plant origin
CAS :6-Chloro-3-indoxyl-beta-D-galactopyranoside is a chromogenic substrate for beta-galactosidase that yields a salmon or rose-coloured precipitate and hence is also known as Salmon-Gal. It can be used in conjunction with isopropyl-beta-D-thiogalactopyranoside (IPTG) as an alternative to the chromogenic substrate 5-bromo-4-chloro-3-indolyl beta-D-galactopyranoside (X-Gal) for detection of beta-galactosidase activity in bacterial colonies in colorimetric assays. Where beta-galactosidase expressed from a reporter gene in molecular biology experiments, recombinant colonies on growth plates are salmon-coloured while non-recombinants appear as white. Use of nitroblue tetrazolium salt (NBT) with Salmon-Gal may provide faster results, yielding a clear, purple precipitate, than for Salmon-Gal alone. In conjunction with 5-bromo-4-chloro-3-indolyl-beta-D-glucoside (X-Glc), Salmon-Gal is useful for simultaneous detection of GUS and Lac activities in the same medium.Formule :C14H16ClNO6Degré de pureté :Min. 98.0 Area-%Masse moléculaire :329.74 g/mol5-Bromo-6-chloro-3-indoxyl phosphate, disodium salt monohydrate
