Substrats d'enzymes
Les substrats enzymatiques sont des molécules sur lesquelles les enzymes agissent pour catalyser des réactions chimiques. Le substrat se lie au site actif de l'enzyme, où il subit une transformation spécifique pour former le produit de la réaction. Les substrats enzymatiques sont des outils essentiels dans la recherche pour étudier la cinétique enzymatique, la spécificité et le mécanisme d'action. Ils sont également utilisés dans les essais diagnostiques et les études biochimiques. Chez CymitQuimica, nous offrons une sélection diversifiée de substrats enzymatiques de haute qualité pour soutenir vos recherches en enzymologie et biochimie.

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/molL-Lysyl-L-alanine 7-amido-4-methylcoumarin dihydrochloride
