<p>5-Bromo-4-chloro-3-indolyl b-D-lactopyranoside is a chromogenic substrate used to detect the specific enzymatic activity of beta-galactosidase. 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 b-D-lactopyranoside is used in lactose intolerance screening.</p>

<p>Aldol® 470 beta-D-galactopyranoside is a chromogenic and fluorogenic enzyme substrate used for detection of beta-galactosidase activity. The colorless enzyme substrate is cleaved by lactose-utilizing bacteria grown in liquid or solid media, yielding yellow coloration and green fluorescence. Aldol® 470 beta-D-galactopyranoside can also be used in beta-galactosidase gene reporter assays or immunoassay applications (ELISA). Aldol® 470 beta-D-galactopyranoside can be used under aerobic and anaerobic conditions.</p>

<p>2-Nitrophenyl butyrate is a chromogenic enzyme substrate that is commonly used in enzymatic assays to detect lipases and esterases. When hydrolyzed by these enzymes, the substrate yields a yellow product that can be detected spectrophotometrically at 405 nm. The advantage of using 2-nitrophenyl butyrate is its high sensitivity and specificity for detecting lipolytic and esterolytic activities. This substrate is widely used in various applications, including enzyme kinetics studies, inhibitor screening, and the determination of esterase activity in biological samples such as serum, plasma, and cell lysates.</p>

<p>A substrate for visualising alkaline phosphatase activity. Produces a red colored insoluble end product that is detected visually, when used together with nitroblue tetrazolium. The substrate system is versatile and functions in a variety of applications, including Northern, Southern, and Western blotting, in situ hybridization, ELISAs and immunohistochemistry. DMF soluble.</p>

<p>5-Bromo-6-chloro-3-indoxyl sulfate, potassium salt is a fluorogenic substrate for the enzyme alkaline phosphatase. This compound is used in the detection of alkaline phosphatase activity as well as in many other applications such as diagnostic tests and environmental testing. 5-Bromo-6-chloro-3-indoxyl sulfate, potassium salt is available at high purity and quality.</p>

<p>5-Bromo-4-chloro-1-methyl-3-indolyl-β-D-glucopyranoside is a fluorescent substrate used for the detection of β-glucuronidase. It can be used in several enzyme substrates, such as 5,5'-dithiobis(2-nitrobenzoic acid), 5,5'-dithiobis(3,4,5,-trimethoxybenzoic acid), and 4-(p-[N-(7-(2,7'-dimethyl -2H -chromenyl)-2H -indazolium)]phenylazo)benzoic acid. This product is used for diagnostics and culture media as well as food testing. The product has an extremely high purity and a CAS number.</p>

<p>5-Bromo-4-chloro-3-indoxyl-alpha-L-arabinofuranoside is a fluorogenic substrate. It is also used as a ligand to detect the presence of an enzyme in a sample. 5BCIAF may be used as an enzyme substrate to measure the activity of enzymes such as beta-galactosidase, alpha-glucuronidase, and esterases. It is also used for diagnostic purposes, with the most common use being for the detection of Mycobacterium tuberculosis in clinical specimens. 5BCIAF can be conjugated to other compounds to form fluorescent probes for detecting specific compounds or cells within a sample. This compound has been shown to have activity against bacteria, fungi, and viruses when tested in culture media and food samples. The chemical structure of 5BCIAF is similar to that of fluorescein, which has been shown to have chemiluminescent properties</p>
