CAS:[2-Methoxy-4-(2-nitrovinyl)phenyl] b-D-galactopyranoside (MNVP-gal) is a chromogenic enzyme substrate that is commonly used to detect the activity of beta-galactosidase in biological samples. MNVP-gal produces a distinctive magenta color when hydrolyzed by beta-galactosidase, making it particularly useful for applications where visual detection is necessary. This substrate is also resistant to endogenous proteases, making it well-suited for use in cellular and tissue preparations.Purity:Min. 95%Molecular weight:357.31 g/mol4-Nitrophenyl 6'-deoxy-6'-(2-pyridylamino)-a-D-penta-(1-4)-glucopyranoside
CAS:4-Nitrophenyl 6'-deoxy-6'-(2-pyridylamino)-a-D-penta-(1-4)-glucopyranoside is a fluorescent substrate for the enzyme beta glucosidase. It is a chemiluminescent reagent that can be used to measure beta glucosidase activity. The substrate is an excellent high quality chemical and has been tested for environmental safety, heavy metal content and staining. 4-Nitrophenyl 6'-deoxy-6'-(2-pyridylamino)-a-D-penta-(1-4)-glucopyranoside is a chromogenic substrate that can be used in diagnostic testing, such as bioluminescence or fluorogenic assay. This product can also be used as a culture media additive or food testing agent.Purity:Min. 95%Molecular weight:1,025.91 g/mol4-Nitrophenyl 4-O-(b-D-mannopyranosyl)-b-D-glucopyranoside
4-Nitrophenyl 4-O-(b-D-mannopyranosyl)-b-D-glucopyranoside is a fluorogenic substrate that can be used for the detection of β-glucosidase activity in biological samples. It is an excellent substrate for the enzyme β-glucosidase, which catalyzes the hydrolysis of ester bonds in glycosides with release of glucose and formation of a phenolic product. The 4-nitrophenol group reacts with oxygen to produce light, making it useful as a chemiluminescent or bioluminescent substrate. The conjugate may also be used to detect β-glucosidase activity in culture media by adding the substrate to the culture medium and measuring its fluorescence. 4NP4OBG has been shown to have high purity, with only trace amounts of impurities detected such as benzaldehyde and 2,6-dinitroPurity:Min. 95%Molecular weight:463.39 g/mol
