Substrati enzimatici

4-Methylumbelliferyl alpha-L-idopyranosiduronic acid 2-sulfate disodium salt is a chromogenic substrate that is used in the detection of glycosidases. It reacts with enzymes such as alpha-amylase, beta-galactosidase, and beta-glucosidase to produce a fluorescent product. This product can be detected using a fluorometer or spectrophotometer. The CAS number for 4-methylumbelliferyl alpha-L-idopyranosiduronic acid 2-sulfate disodium salt is 1045020-74-3.

Aldol® 518 alpha-D-glucopyranoside is a fluorogenic enzyme substrate used for detection of alpha-D-glucosidase activity. The colorless enzyme substrate is cleaved by alpha-D-glucosidase, generating red fluorescent signal and in some conditions, an orange colour in the visible spectrum can get formed, staining bacterial colonies in faint orange coloration. Aldol® 518 alpha-D-glucopyranoside can be used under aerobic and anaerobic conditions.

Luc-Enterococcus K is a conjugate of the bacterial luciferase enzyme and Enterococcus faecalis. It is used in food testing, environmental testing and diagnostics. Luc-Enterococcus K can be used as a replacement for the fluorogenic substrate luminol, which is difficult to handle because it has to be kept cold during use and is explosive. Luc-Enterococcus K produces light when it reacts with the chromogenic substrate luciferin, which can be stored at room temperature without degrading. The light produced by Luc-Enterococcus K is blue green in color, making it easy to detect with a camera or eye.

Chromogenic substrate for alpha-glucosidase

Its mechanism of action involves interfering with ergosterol biosynthesis, an essential component of fungal cell membranes. Furthermore, this compound has potential applications in the development of new drugs targeting GSK-3β and β-catenin signaling pathways, which are implicated in various diseases including cancer and neuro

Luc-Listeria Na is a conjugated substrate for the detection of Listeria monocytogenes in food, environmental and clinical samples. It is a high purity product that can be used for the detection of Listeria monocytogenes from culture media, bioluminescence, chromogenic substrate, and fluorogenic substrate. Luc-Listeria Na is also a ligand for ELISA and IHC assays.

4-Nitrophenyl phosphate bis(cyclohexylammonium) is an excellent chromogenic substrate designed for the detection and quantification of phosphatase enzyme activities. Aided by the presence of the cyclohexylammonium cation, it undergoes enzymatic hydrolysis, yielding the colored 4-nitrophenolate ion, which can be readily observed at 405 nm. The substrate has become an essential tool for biomedical research, playing a crucial role in unearthing cellular mechanisms, function, and potential drug targets.

AquaSpark® Peroxide Probe is a dioxetane-based substrate for the luminescence detection of hydrogen peroxide and other peroxides in biological samples.
