Sustratos de enzimas
Los sustratos enzimáticos son moléculas sobre las cuales actúan las enzimas para catalizar reacciones químicas. El sustrato se une al sitio activo de la enzima, donde sufre una transformación específica para formar el producto de la reacción. Los sustratos enzimáticos son herramientas esenciales en la investigación para estudiar la cinética enzimática, la especificidad y el mecanismo de acción. También se utilizan en ensayos diagnósticos y estudios bioquímicos. En CymitQuimica, ofrecemos una selección diversa de sustratos enzimáticos de alta calidad para apoyar su investigación en enzimología y bioquímica.

4-Methylumbelliferyl-beta-D-glucuronic acid dihydrate
CAS:4-Methylumbelliferyl beta-D-glucuronide (MUG) is commonly used as a substrate for detecting beta-glucuronidase. MUG is used for identifying E. coli contamination in food, drinking water, clinical samples and for rapid bacterial identification in blood cultures.

MUG is also a tool assaying the glucuronidase gene in plants.Fórmula:C16H20O11Pureza:Min. 99 Area-%Peso molecular:388.33 g/mol6-(b-D-Galactopyranosyloxy)-9-(4-methoxy-2-methylphenyl)-3H-xanthen-3-one
CAS:6-(b-D-Galactopyranosyloxy)-9-(4-methoxy-2-methylphenyl)-3H-xanthen-3-one (MGBG) is a hydrophilic activatable fluorescence probe that has been shown to be effective in photodynamic therapy. MGBG is activated by light and has a high affinity for esterases, which are found in many tissues. The fluorescence of the MGBG is quenched by the esterase enzymes, but when it is exposed to light and oxygen, the probe becomes activated and its fluorescence increases. MGBG can be used as a fluorescent probe for intraperitoneal tumor resection or as a fluorescent imaging agent in optical microscopy.Pureza:Min. 95%Peso molecular:494.49 g/molD-Luciferin Firefly, sodium salt monohydrate
