Glutathione is the major low molecular weight thiol compound of the living plant or animal cell. It is a tripeptide with a gamma peptide linkage between the amine group of cysteine (which is attached by normal peptide linkage to a glycine) and the carboxyl group of the glutamate side-chain. It is…

Salicin is a substrate for β-glucosidase.

A chromogenic substrate for Plasmogen Activator Serine Protease

Boc-VLGR-pNA acetate salt (sequence Boc-Val-Leu-Gly-Arg-pNA), is a chromogenic substrate for horseshoe crab clotting enzyme. It has been widely used in detection assays for bacterial endotoxins. 25 mg, 100 mg

Ac-Trp-Glu-His-Asp-AFC

A modified tripeptide reversible protease inhibitor of trypsin-like proteases and some cysteine proteases including endoproteinase Lys-C, kallikrein, papain, thrombin, cathepsin B, cathepsins H and L, trypsin, calpain, trypsin and plasmin. Little to no inhibition is seen against pepsin, cathepsins…

Glutathione suppresses human immunodeficiency virus expression in chronically infected monocytic cells. It is a useful tripeptide involved in many aspects of metabolism, including transport of g-glutanyl amino acids and reductive cleavage of disulfide bonds.

o-Nitrophenyl-β-D-galactoside (ONPG) is a colorimetric substrate for b-galactosidase. This product is hydrolyzed to o-nitrophenol by the enzyme. o-Nitrophenol is yellow in alkaline solution and can be quantitated at 410-420 nm 2 . o-Nitrophenyl-β-D-galactoside is a cell culture…

(TMB Powder) This product is excellent for ELISA procedures. C₁₆H₂₀N₂ MW 240.3

Gly-Phe-AFC is a fluorogenic, cell-permeant peptide substrate, used in Cytotoxicity testing. In vitro cytotoxicity testing has become an integral aspect of drug discovery because it is a convenient, costeffective, and predictive means of characterizing the toxic potential of new chemical entities. …

2,2′-Azino-bis(3-ethylbenzthiazoline-6-sulfonic acid) is a peroxidase substrate suitable for use in ELISA procedures. This substrate produces a soluble end product that is green in color and can be read spectrophotometrically at 405 nm. The reaction may be stopped with 1% sodium dodecyl…

Ac-DEVD-AFC is a sensitive fluorescent substrate for the assay of caspase-3 activity. The trifluoromethyl substituent of the fluorophore improves the membrane permeability of the substrate.

Sodium azide is used as a preservative for laboratory reagents; a bacteriostatic agent in storage solutions. Inhibits gram negative flora so is therefore included in culture media for the selective isolation of Streptococci and Staphylococci. It has been used to avoid bacterial contamination during…
