PAIRED PRODUCT AVAILABLE: alpha-L-iduronidase Enzyme, FI179383.
4MU-alpha-L-idopyranosiduronic acid is a fluorogenic substrate for alpha-L-iduronidase. Active alpha-L-iduronidase cleaves the MU moiety from the synthetic substrate, which results in release of a fluorescent signal (Ex 360 nm / Em 455 nm). The reaction is stopped by the addition of sodium carbonate. 4MU-alpha-L-idopyranosiduronic acid is used in alpha-L-iduronidase assays in the context of biochemical characterisation of samples from patients affected by lysosomal storage disease mucopolysaccharidosis I (MPS I).

Chromogenic substrate targeting alpha-L-arabinofuranosidase

4-Nitrophenyl a-D-mannopyranoside is a chromogenic pNP enzyme substrate that enables the detection and quantification of a-D-mannosidase activity in various biological samples through a colorimetric assay. The hydrolysis of the substrate by the enzyme releases 4-nitrophenol, a yellow compound whose absorption can be measured spectrophotometrically. Applications for this substrate span biomedical research, disease diagnostics, and industrial enzyme production.

5-Bromo-4-chloro-3-indoxyl-1-acetate is a chromogenic substrate used to detect the specific enzymatic activity of esterase. After cleavage, 5-bromo-4-chloro-indoxyl is released, resulting in a blue to blue-green color change in bacterial colonies or media. 5-Bromo-4-chloro-3-indoxyl-1-acetate is used in bacterial esterase activity assays (e.g. Pseudomonas spp.).

The DDAO molecule [7-hydroxy-9H-(1, 3-dichloro-9, 9 dimethylacridin-2-one] is used as a stain and a dye in molecular biology, due to its ability to bind intracellular and extracellular DNA. DDAO galactoside is a fluorogenic substrate for galactosidase.

Luc-Salmonella is a conjugate of the enzyme luciferase and the substrate 5-bromo-4-chloro-3-indolyl phosphate. Luc-Salmonella has been used for diagnostic purposes in the detection of bacteria in culture media, as well as in environmental and food testing. Luc-Salmonella can be used to detect Salmonella, which is a bacterium that can cause gastrointestinal disease. Luminescence is measured using a luminometer or fluorimeter with an excitation wavelength of 485 nm and emission wavelengths at 510 nm. Luminescence from Luc-Salmonella is typically measured after 1 hour incubation with bacterial cells.
Luc-Salmonella has been shown to have high purity and quality due to its unique composition of enzyme substrate. This product has been tested for contamination by sensitive assays such as chemiluminescence, bioluminescence, or fluorescence. The purity level of Luc-Sal

A substrate used for the diagnosis of Sanfilippo disease C (MPS III C).

L-Serine 7-amido-4-methylcoumarin hydrochloride is a fluorogenic peptide substrate for peptidases. This AMC peptide substrate is normally used to rapidly profile the N-terminal specificity of proteases.

Modified naphtol AS substrate used in histochemical and cytochemical staining

2-Chloro-4-nitrophenyl a-D-maltotrioside (2CNP) is a potent hypoglycemic agent that has been shown to decrease postprandial blood glucose levels in humans. 2CNP is a white crystalline solid that is soluble in water and ethanol. The transfer reactions of 2CNP are enhanced by benzalkonium chloride, which forms an organic complex with the drug. The optimum concentration for the hypoglycemic effect of 2CNP is determined to be 10 μM, which can be detected using an optical sensor. This compound also inhibits α-amylase and other enzymes involved in carbohydrate metabolism, leading to the accumulation of glycogen and lowering the blood glucose level.
