Guanosine-5'-triphosphate, a purine nucleotide, is required as a coenzyme for protein biosynthesis in a cell-free system. Guanosine 5′-triphosphate (GTP), a purine trinucleotide, is a substrate for RNA polymerases and a wide range of GTPase including G-protein coupled receptor (GPCR)…

Phenazine ethosulfate is an intermediate which is used to detect nitric oxide reducatase activity in concert with ascorbic acid.

SDS is an anionic detergent and wetting agent that is effective in both acid and alkaline solutions. Most proteins bind SDS in a ratio of 1.4 grams SDS to 1 gram protein. The charges intrinsic to the protein become insignificant compared to the overall negative charge provided by the bound SDS. The…

D-(+)-Maltose Monohydrate is an α(1→4) linked disaccharide of D-glucose. D-(+)-Maltose Monohydrate is used as a substrate for α-glucosidase. It is also used as a substrate for the identification, differentiation and characterization of enzymes such as maltase(s); maltose…

Sucrose is a simple carbohydrate. A disaccharide composed of glucose and fructose, which is used for a variety of applications. It is isolated from cane sugar; it is not synthetic. Sucrose can be used to prepare density gradients for cell/organelle separation. The refractive index of the…

Triolein is a symmetrical triglyceride. Triolein is used as a substrate for microbial lipases.

Uridine-5'-diphosphogalactose Disodium Salt is a donor substrate for galactosyltransferases involved in the addition of galatose (galactosylation) molecules to N-linked and O-linked oligosaccharides and glycerolipids(biosynthesis of galactose-containing oligosaccharides). UDP-Gal and its…

A naturally occurring aromatic compound. Contains varying amounts of poly(styrene oxide). Phenylacetaldehyde is used for the preparation of fragrances and polymers like polyesters, which find application as a rate controlling additive in polymerization reactions. It is an active component of…

Cathepsin G is a serine protease that degrades collagen and proteoglycans. It has been implicated in connective tissue-related disorders. Cathepsin G from human leukocytes is a glycoprotein containing approximately 1% carbohydrate. It is considered to be a major constituent of human neutophil…

Muscone, originally collected from male musk deer ventral glands, is a potent antiinflammatory agent that has been reported to reduce proinflammatory cytokines in vitro. This compound has also been shown to reverse IL-1β-induced upregulation of IL-1β, TNFα, NOS2 (inducible nitric…

Fibronectins are adhesive glycoproteins and are found both as cell surface proteins and in plasma. Human fibronectin (HFN) is suitable for use as an attachment factor in the propagation of cells in vitro when used to coat cell culture surfaces, including plasticware, glassware, and…

Hygromycin B is an antibiotic substance isolated from Streptomyces hygroscopicus. Its mode of action is the inhibition of protein synthesis, by inducing the misreading of the m-RNA template in the prokaryote, (E. coli, at 100 mg/mL), lower eukaryotes (e.g., yeast, at 200 mg/mL) and higher…

Ivermectin is a macrolide antiobiotic, & semisynthetic derivative of avermectin B1a and B1b. Ivermectin is a broad-spectrum antiparasitic agent. Positive allosteric modulator of α7 neuronal nicotinic acetylcholine receptor; also modulates glutamate-GABA-activated chloride channels.
