(+)-Biotin 4-amidobenzoic acid sodium salt, often referred as (+)-biotin PABA, is a fluorogenic substrate used to measure biotinidase activity, especially in newborn screening programs.

2-Nitrophenyl-1-thio-beta-D-galactopyranoside is a nitroaryl compound that can be synthesized from beta-D-galactopyranosides and nitric acid. It has a molecular conformation that is stabilized by hydrogen bonds, which allows it to form supramolecular assemblies with other molecules. The nitro group in this molecule is responsible for the formation of the nitro group in 1,2,4,5,-tetranitrobenzene.

6-Chloro-3-indolyl b-D-cellobioside is a chromogenic substrate that produces a salmon-pink color after enzymatic cleavage. It is used for detecting the activity of beta-D-cellobiosidase in enzyme assays.

Nalpha-CBZ-L-Citrulline-p-nitroanilide is a synthetic chromogenic enzyme substrate used in protease enzymatic stutides. After hydrolysis, p-nitroaniline is released, which produces a yellow color detectable spectrophotometrically at 405 nm.

4-Methylumbelliferyl palmitate, commonly names as 4-MUP, is a fluorescent probe that binds to lipases, enzymes responsible to assist on the hydrolysis of fats. In diagnosis, 4-MUP is used for screening of lysosomal storage diseases (LSD) caused by a deficiency of a single enzyme involved in the metabolism of glycoproteins, lipids or mucopolysaccharides.

Aldol® 470 acetate is a Fluorogenic substrate that is used in enzymatic reactions to produce a fluorescent product. Aldol® 470 acetate can be used as a ligand or a chromogenic substrate. This product is also used in diagnostic tests, such as conjugates and chemiluminescence, to detect the presence of certain enzymes or microorganisms. It can be used in culture media to measure the amount of certain enzymes, such as phosphatases or proteases, and has been shown to have high purity and quality. This product has CAS No. 1318785-37-3, 1318785-38-4, 1318785-39-5, 1318785-40-6 and 1318785-41-7.

5-Bromo-6-chloro-3-indolyl acetate is a chromogenic substrate that yields a magenta-colored product after cleavage. The chromophore 5-bromo-6-chloro-indoxyl is released, generating the observable color. It is used in bacterial esterase detection (e.g. Staphylococcus spp.).

Luciferin-alpha-D-galactoside, sodium salt (LDA) is a bioluminescence substrate. It is used in diagnostic tests for the detection of bacteria and fungi. LDA is also used to measure the effectiveness of biocides and disinfectants. This product has been shown to be a potent fluorogenic substrate in chemiluminescent assays that can be used effectively with firefly luciferase.
