5-Bromo-3-indolyl phosphate disodium salt is a chemiluminescent substrate that is used for the detection of bacterial activity. It reacts with oxygen to produce light, which can be measured using a luminometer. It is also used as a chromogenic substrate for detection of bacterial activity in culture media. The enzyme reaction produces an intense blue fluorescence and is used for diagnostic purposes in food testing and medical diagnostics. 5-Bromo-3-indolyl phosphate disodium salt has been shown to be effective against many bacteria and fungi, including Staphylococcus aureus, Streptococcus pyogenes, Escherichia coli, Pseudomonas aeruginosa, Candida albicans and Aspergillus niger. This product is chemically stable at room temperature but should be stored at 4°C or below.

2-Chloro-4-nitrophenyl a-D-maltotrioside (2CNP) is a potent hypoglycemic agent that has been shown to decrease postprandial blood glucose levels in humans. 2CNP is a white crystalline solid that is soluble in water and ethanol. The transfer reactions of 2CNP are enhanced by benzalkonium chloride, which forms an organic complex with the drug. The optimum concentration for the hypoglycemic effect of 2CNP is determined to be 10 μM, which can be detected using an optical sensor. This compound also inhibits α-amylase and other enzymes involved in carbohydrate metabolism, leading to the accumulation of glycogen and lowering the blood glucose level.

3-Indoxyl phosphate, p-toluidine salt is a fluorogenic substrate that can be used for the detection of β-galactosidase. 3-Indoxyl phosphate, p-toluidine salt is a highly active chromogenic substrate that can be used as a diagnostic tool in the food industry to determine whether or not milk has been adulterated with animal milk. This product is also used in environmental testing to detect bacteria and fungi. 3-Indoxyl phosphate, p-toluidine salt is a high purity, high quality conjugate that can be used for the detection of β-galactosidase.

Chitin azure is a chromogenic substrate for chitinases. It is one of the few specific substrates for this enzyme that produces chito-oligosaccharides from chitin.

4-Nitrophenyl-alpha-D-glucopyranoside, beta-Anomer is a chromogenic sugar that can be used as an indicator for the presence of 4-nitrophenol. It is a highly reactive compound that spontaneously reacts with nitrobenzene to form a dinitroaniline. This anomeric structure is easily oxidized by air and light to form the corresponding o-dinitroaniline. When this reaction occurs, this substance changes color from yellow to red.

Aldol® 515 L-alanine amide is a chromogenic and fluorogenic enzyme substrate used for detection of L-alanine aminopeptidase activity. The colorless enzyme substrate is cleaved by L-alanine aminopeptidase produced by microorganisms, grown in liquid or solid media yielding red color. In addition, red fluorescence is generated when a fluorescence enhancer or a suitable matrix is present. Aldol® 515 L-alanine amide can be used under aerobic and anaerobic conditions.

Ostazin Brilliant Red H-3B Galactomannan is a chemiluminescent substrate used for the detection of β-1,4-galactomannans. It reacts with the glucose residues on the mannan backbone to produce a red fluorescent product. This product can be detected by spectrophotometry at an excitation wavelength of 395 nm and emission wavelength of 510 nm. The Ostazin Brilliant Red H-3B Galactomannan substrate is useful in detecting Staphylococcus aureus, Streptococcus pyogenes, Streptococcus pneumoniae, Group A streptococci, Group B streptococci, Group D streptococci, Group G streptococci, and Group C streptococci.

5-Bromo-4-chloro-3-indolyl b-D-fucopyranoside is a chromogenic substrate used is for the enzyme beta-fucosidase.
