Catalog ID Size Pricing

M-310-25 25 g $ 1,353.00

Description

1-O-Methyl-β-D-glucuronic acid, sodium salt is an inducer of β-glucuronidase, a glycosidase enzyme coded by the GUS gene.

The GUS gene is the most extensively used reporter gene, particularly in plant biology because it offers the advantage of having no background activity.

β-glucuronidase also has an important role within human digestion because this enzyme is capable of deconjugating toxins within the body and releasing them back freely into the bloodstream. There is a positive relationship between higher levels of β-glucuronidase in the colon and increased cancer risk. However, β-glucuronidase, at certain levels, is necessary, and deficiencies can result in mucopolysaccharidosis type VII or Sly syndrome in newborns.

Description

Tetrazolium red is used to visualize dehydrogenase enzyme activity. Initially, the tetrazolium solution is colorless but changes to red when it comes into contact with hydrogen. Tetrazolium red is used in a biochemical viability test for seeds. The test relies on dehydrogenase enzymes to release hydrogen ions, which subsequently reduce the colorless tetrazolium salt solution to a red compound called formazan. Living cells turn red while dead cells remain colorless.

Description

4-Methylumbelliferyl palmitate is used as a fluorogenic substrate for a subclass of esterases called lipase.

Lipase is an enzyme that assists in the hydrolysis of fats. They have a large role in digestion as well as dietary lipid transport.

Lysosomal acid lipase (LAL), in particular, is required for the hydrolysis of cholesterol esters which are then delivered into the lysosome. Deficiencies in LAL are primarily associated with two diseases: cholesteryl ester storage disease (CESD) and Wolman’s disease (WD). 4-Methylumbelliferyl palmitate has often been used as one of the lipase substrates in studies involving either of these diseases.

Description

4-Methylumbelliferyl phosphate (MUP) is a sensitive fluorogenic substrate for fluorometric and UV-spectrophotometric assays of phosphatase.

Phosphotase activity has long been studied due to its importance in cellular function. Upon dephosphorylation, MUP yields fluorescent 4-methylumelliferone (4-MU). This reaction has been used to spot PCR amplified products in ELISA and to classify bacteria.

More specifically, MUP can act as an indicator of C. perfringens because of its ability to detect phosphatase which is a highly specific indicator of C. perfringens.
