Enzymes are important biological macromolecules that allow for the control of cellular functions and are vital for effective research. Enzyme activity can be slowed or stopped using inhibitors, like Proteinase K or RNase, while substrates like X-Gluc and X-Gal are used in detection and monitoring. D-Luciferin Potassium Salt, our most popular bioluminescent substrate, can be used for in vivo and in vitro imaging. GoldBio knows that having high quality enzyme tools are important to your laboratory, and we are committed to delivering quality products at a fraction of the price.

Description
1-Dodecylimidazole is grouped with the imidazole organic compounds, containing an imidazole 1,3-C3N2 ring produced by natural products like alkaloids. Imidazole is amphoteric and aromatic. When an additional carbon and two hydrogens bind to the ring of this compound, 1-Dodecylimidazole can produce a 1-dodecyl-3-methylimidazolium cation. As an antifungal, 1-Dodecylimidazole can inhibit sterol C14 demethylation at low levels, 2,3-oxidosqualene cyclization and subsequent transmethylation when the quantity is raised. This has been postulated as a result of its binding to sterol carrier proteins. It functions as a hypocholesterolaemic agent by inhibiting cholesterol biosynthesis at the level of 2,3-oxidosqualene sterol cyclase. This substance has been an View product page →

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

P-aminophenyl phosphate (pAPP) can be used as a substrate for alkaline phosphatase enzymatic reactions in order to electrochemically quantify ALP activity.

The enzymatic reaction results in the production of phenol, which can be quantified and used to analyze ALP concentrations.

ALP is a naturally occurring enzyme and can be found in human tissue in the liver, bone and intestines. Usual concentrations of ALP range between 25-100 IU/L. A significant spike outside of that range could act as a signal for many diseases.

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.
