Cat. No.: HY-137858
CAS No.: 125455-61-0
Synonyms: Gly-Arg-4-NA hydrochloride; GR-pNA hydrochloride; GR p-itoailide hydrochloride
H-Gly-Arg-pNA hydrochloride (GR-pNA hydrochloride) is a colorimetric substrate for thrombin. H-Gly-Arg-pNA is preferentially bound by thrombin and cleaves the Gly-Arg (GR) peptide sequence, releasing p-nitroaniline (pNA) that can be detected colorimetrically at 405 nm. H-Gly-Arg-pNA hydrochloride is used as a fluorescent dye to measure thrombin activity .

Cat. No.: HY-D1224A
CAS No.: 99792-50-4
Synonyms: CPRG sodium
Chlorophenol red-β-D-galactopyranoside (CPRG) sodium is an efficient and sensitive chromogenic substrate for β-galactosidase (HY-P2869), widely used in colorimetric assays. Chlorophenol red-β-D-galactopyranoside sodium itself appears pale yellow. When it is specifically hydrolyzed by β-galactosidase, it releases chlorophenol red. The released chlorophenol red turns purple-red under alkaline or neutral pH conditions. This color change from yellow to red can be quantitatively detected at wavelengths of 540-572 nm using visible spectrophotometry .

D-Val-Leu-Lys-pNA (S-2251) is a chromogenic peptide substrate that serves as a characteristic substrate for plasmin and plasminogen. D-Val-Leu-Lys-pNA acts as a sensitive substrate for the DFE27 serine protease derived from Bacillus subtilis DC27. Catalyzed by plasmin, D-Val-Leu-Lys-pNA binds and hydrolyzes to release p-nitroaniline (pNA), which can be detected colorimetrically at 405 nm as a measure of fibrinolytic activity .

Cat. No.: HY-W009458
CAS No.: 3318-43-2
Synonyms: 3-IP sodium
3-Indoxyl phosphate (3-IP) is a chromogenic and electrochemical substrate for alkaline phosphatase. Upon enzymatic cleavage by alkaline phosphatase, 3-indoxyl is released and subsequently oxidized to produce water-insoluble indigo, which can be quantified by colorimetric detection at 660 nm as a measure of alkaline phosphatase activity. 3-Indoxyl phosphate can also be converted to water-soluble leucoindigo by reduction of indigo in alkaline solution by sodium dithionite, which can be quantified by colorimetric detection at 415 nm or voltametric detection as a measure of alkaline phosphatase activity.2 3-Indoxyl phosphate has been used in ELISAs.

PS-915 dihydrochloride is a peptide substrate used in a colorimetric assay for plasma antithrombin III (ATIII). PS-915 dihydrochloride is highly specific for thrombin. By enzyme hydrolysis, PS-915 dihydrochloride liberates 3-carboxy-4-hydroxyaniline (CHA), which turns blue in color due to the complex formation with added alkaline-pentacyanoammine ferroate .

Cat. No.: HY-120971
CAS No.: 72298-63-6
Synonyms: DepNA
N-Decanoyl p-nitroaniline (DepNA) is one of several nitroaniline fatty acid amides which can be used to measure fatty acid amide hydrolase (FAAH) activity.1 FAAH is a relatively unselective enzyme in that it accepts a variety of amide head groups other than the ethanolamine of its endogenous substrate anandamide (AEA). It also will hydrolyze fatty acid amides with fewer carbons and fewer double bonds than arachidonate. Exposure of DepNA to FAAH activity results in the release of the yellow colorimetric dye p-nitroaniline (ε=13,500 at 410 nm). This allows the fast and convenient measurement of FAAH activity using a 96 well plate spectrophotometer.
