Substrati enzimatici
I substrati enzimatici sono molecole su cui agiscono gli enzimi per catalizzare reazioni chimiche. Il substrato si lega al sito attivo dell'enzima, dove subisce una trasformazione specifica per formare il prodotto della reazione. I substrati enzimatici sono strumenti essenziali nella ricerca per studiare la cinetica enzimatica, la specificità e il meccanismo d'azione. Sono utilizzati anche in saggi diagnostici e studi biochimici. Presso CymitQuimica, offriamo una selezione diversificata di substrati enzimatici di alta qualità per supportare le vostre ricerche in enzimologia e biochimica.

AquaSpark® 510 acetate, 10 mM in DMSO, Ramot at Tel-Aviv University Ltd. Patent family WO 2017/130191
CAS:AquaSpark® 510 acetate is a dioxetane-based luminogenic substrate for C2-esterase (acetyl esterase) activity. Upon hydrolytic cleavage by the enzyme AquaSpark® 510 acetate spontaneously emits green light.

In microbiology C2-esterase activity can be used to detect specific microorganisms such as Bacillus cereus, Pseudomonas aeruginosa, Campylobacter jejuni and Candida albicans.
Formula:C30H31ClO8Peso molecolare:554.17 g/mol5-Bromo-4-chloro-3-indoxyl-β-D-galactopyranoside
CAS:X-Gal is a chromogenic substrate for β-galactosidase, yielding a blue precipitate. X-Gal is an indicator for coliforms in culture media, as well as for the detection of coliforms (E. coli) in municipal water supplies and food products. X-Gal can be used in conjunction with the inducer IPTG, which binds and inhibits the lac repressor thus inducing β-galactosidase expression. X-Gal is the substrate of choice for blue-white selection of recombinant bacterial colonies with the lac+ genotype. Upon hydrolysis, X-Gal yields a localized, insoluble, blue precipitate, making it exceptionally useful in blotting, immunocytochemical, and ELISA assays. 5-Bromo-4-chloro-3-indoxyl-beta-D-galactopyranoside (X-beta-D-galactoside, X-Gal) is a chromogenic indicator for beta-galactosidase activity. The colorless product is cleaved by lactose-utilizing bacteria in liquid media or on agar plates and yields a blue-green colored precipitate. X-Gal can also be used as a detecting agent for beta-galactosidase activity in reporter gene assays or for identification of positive transformants on agar plates when using the α-complementation approach. Color formation is due to dimerization and oxidation of 5-bromo-4-chloro-3-hydroxyindole which results from enzymatic cleavage of X-Gal. The reaction proceeds only in the presence of oxygen, i.e. in aerobic cultures. Well detectable color bacterial colonies or liquid cultures is obtained within 16-48 h. In the presence of purified beta-galactosidase, color develops within minutes to a few hours.Formula:C14H15BrClNO6Purezza:Min. 99.0 Area-%Peso molecolare:408.64 g/molAquaSpark® beta-D-galactoside, 10 mM in DMSO, Ramot at Tel-Aviv University Ltd.

CAS:5-Bromo-6-chloro-3-indoxyl choline phosphate is a chemiluminescent substrate for the detection of bacterial activity. It reacts with an enzyme, luciferase, which is present in a variety of living cells. The reaction produces light. This product has been tested for environmental and food safety by the manufacturer. 5-Bromo-6-chloro-3-indoxyl choline phosphate is used as a diagnostic tool to determine the presence of bacteria in humans, animals, and plants. It can be used to measure levels of bacteria in culture media, water samples, and food products. 5-Bromo-6-chloro-3-indoxyl choline phosphate can also be used as a substrate for enzymes such as phosphatases or esterases that catalyze reactions with substrates with brominated or chlorinated groups.Formula:C13H17BrClN2O4PPurezza:Min. 95%Peso molecolare:411.63 g/molResorufin acetate
CAS:Resorufin acetate is a fluorogenic substrate for esterase activity measurments in lipid metabolism studies. It is also used as a substrate for chymotrypsin, a digestive enzyme produced by the pancreas that aids in protein digestion in the small intestine.
