<p>4-Chloro-1-naphthol is a chemical compound that has been used in clinical pathology to identify human immunoglobulin. It is also used as a potential biomarker for the diagnosis of Alzheimer's disease. 4-Chloro-1-naphthol binds to the amyloid fibrils and has anti-angiogenic effects in the hippocampus, which may be due to its ability to inhibit the formation of new blood vessels. This chemical compound can be used as a substrate molecule for electrochemical impedance spectroscopy and is used in wastewater treatment.</p>

<p>5-Bromo-6-chloro-3-indolyl b-D-glucuronide cyclohexylammonium salt is a magenta enzyme substrate commonly used in biochemical assays. This compound is a derivative of indole, containing bromine and chlorine atoms at positions 5 and 6, respectively. The glucuronide moiety is attached to the indolyl ring, and the cyclohexylammonium cation serves as a counterion to balance the charge. This substrate is often utilized in the detection and quantification of β-glucuronidase activity, an enzyme involved in the metabolism of glucuronides. Upon cleavage by β-glucuronidase, the substrate produces a magenta-colored product, allowing for easy visualization and measurement of enzyme activity.</p>

<p>Fluorogenic substrate for β-glucosidase</p>

<p>2-Amino-5-pyridyl 2-acetamido-3,4,6-tri-O-acetyl-2-deoxy-a-D-galactopyranose is a chromogenic substrate for the enzyme β galactosidase. It is used to detect the presence of β galactosidase in bacterial cultures. The substrate is soluble in water and has a long shelf life. 2APAAG can be used for food testing and environmental testing as it produces a bioluminescent signal when cleaved by β galactosidase.</p>

<p>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.</p>

<p>Bronze-Gal (Bronze-beta-D-galactopyranoside) is a chromogenic indicator for beta-galactosidase activity. The colorless product is cleaved by lactose-utilizing bacteria in liquid media or on agar plates and yields a bronze colored precipitate. Bronze-Gal can also be used as detecting agent for beta-galactosidase activity in reporter gene assays or for identification of positive transformants on agar plates when using the α-complementation approach.
