4-(Bromomethyl)phenyl-β-D-triacetylglucuronic acid methyl ester
4-(Bromomethyl)phenyl-beta-D-triacetylglucuronic acid methyl ester, also known as 4-bromo-4'-(N,N-dimethylamino)biphenyl, is a bioluminescent substrate. It is used for the detection of beta-glucuronidase activity in biological samples and for the detection of bacterial β-glucuronidase activity in culture media. Beta-glucuronidase catalyzes the hydrolysis of glucuronic acid by breaking down a conjugate molecule into two smaller molecules, which can be detected using bioluminescence. 4-(Bromomethyl)phenyl-beta-D-triacetylglucuronic acid methyl ester is a chromogenic substrate that has been shown to be an excellent ligand in biomolecular research because it reacts with many different enzymes. This product is highly pure and

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.Formula:C14H16ClNO6Purity:Min. 98.0 Area-%Molecular weight:329.74 g/molIsopropyl-β-D-thiogalactopyranoside, <5ppm dioxane
CAS:IPTG is a gratuitous beta-D-galactosidase inducer. In Escherichia coli IPTG functions by binding to the lac repressor and altering its conformation. This inactivation prevents the repressor binding to the operator of the lac operon and thus the repression of the beta-galactosidase coding gene lacZ. IPTG is a commonly used reagent in cloning procedures that require induction of beta-galactosidase activity and is used in conjunction with X-Gal or Lapis-β-D-Gal in blue-white color selection of recombinant bacterial colonies.Formula:C9H18O5SPurity:Min. 99.0 Area-%Molecular weight:238.30 g/mol4-Nitrophenyl phosphate, bis(cyclohexylammonium) salt

CAS:2-Naphthyl beta-D-galactopyranoside is a glycoside that is found in the flowers of the plant Eschscholzia californica. It is used as a localizer for bacterial strains and can be hydrolyzed by enzymes to release naphthalene. 2-Naphthyl beta-D-galactopyranoside has been shown to inhibit the growth of corynebacterium and diazonium salt, which may be due to its ability to bind to DNA and disrupt protein synthesis. The potential use of this molecule is for its insolubility, which prevents it from being absorbed by skin cells.
