4-Nitrophenyl 2-acetamido-3-O-(2-acetamido-3,4,6-tri-O-acetyl-b-D-glucopyranosyl)-4,6-di-O-acetyl-2deoxy--aDgalactopyranoside is a substrate for enzymes such as beta galactosidase and alpha amylase. It can be used for the detection of these enzymes in biological samples, including culture media and body fluids. 4NPAG has also been used as a chromogenic substrate to measure the activity of NADH oxidase in neutrophils. 4NPAG is fluorescent in aqueous solution and can be used to detect bioluminescence reactions.

Naphthol AS-BI sulphate potassium salt is a modified naphtol AS substrate used for alkaline and acid phosphatase.

Cloprostenol is a synthetic analogue of prostaglandin.

Aldol® 515 nonanoate hydrochloride is a chromogenic and fluorogenic enzyme substrate for detection of lipase activity. The colorless product is cleaved by C9 esterases produced by bacteria in liquid or solid media, yielding a red color and red fluorescence when Aldol® 355 fluorescence enhancer or a suitable matrix is present. Aldol® 515 nonanoate can be used under aerobic and anaerobic conditions. Well detectable color/fluorescence of bacterial colonies or liquid cultures is obtained within 24-48 h. In the presence of a purified lipase, color and fluorescence develops within minutes to few hours.

Aldol® 484 alpha-D-glucopyranoside is a chromogenic and fluorogenic enzyme substrate for ?-glucosidase activity (EC 3.2.1.20, ?-1,4-glucosidase, also known as maltase). The colorless enzyme substrate is cleaved by bacteria producing this enzyme in liquid or solid media, yielding orange color. Green fluorescence is also generated if a suitable matrix is present such as: cellulose acetate filters, polypropylene tubes or microplates and polyethylene vials. Aldol® 484 alpha-D-glucopyranoside can be used under aerobic and anaerobic conditions.

5-Bromo-6-chloro-3-indolyl caprylate (or magenta caprylate) is a chromogenic substrate which can be used for the detection of esterase enzyme activity from Salmonella and some Klebsiella and Enterobacter. The esterase cleaves the ester bond in the substrate, releasing 5-bromo-6-chloro-1H-indol-3-ol which undergoes oxidative dimerization to form 5,5'-dibromo-6,6'-dicholoro-indigo, a magenta coloured chromophore (λmax 565nm). This product is patent pending, as polymorphs of this product can have different physicochemical properties and can improve solubility and stability. Cymit Quimica is able to product high quality, stable product to detect esterase enzyme activity.

Chromogenic substrate for beta-glucuronidase

Aldol® 518 alpha-D-glucopyranoside is a fluorogenic enzyme substrate used for detection of alpha-D-glucosidase activity. The colorless enzyme substrate is cleaved by alpha-D-glucosidase, generating red fluorescent signal and in some conditions, an orange colour in the visible spectrum can get formed, staining bacterial colonies in faint orange coloration. Aldol® 518 alpha-D-glucopyranoside can be used under aerobic and anaerobic conditions.

BIOSYNTH Culture Medium for the isolation andidentification of Escherichia coli O157:H7

5-Bromo-4-chloro-3-indolyl myristate is a chromogenic substrate used to detect the specific enzymatic activity of lipase or esterase. After cleavage, 5-bromo-4-chloro-indoxyl is released, resulting in a blue to blue-green color change in bacterial colonies or media. 5-Bromo-4-chloro-3-indolyl myristate is used in screening assays for pancreatic lipase deficiency and lipid metabolism studies.
