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.

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.

Chemiluminescent phosphatase substrate in a wide pH range (pH 6 - 10)

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.

AquaSpark® Enhanced HRP Detection Solution is a sensitive chemiluminescent substrate solution for detecting horseradish peroxidase (HRP) conjugates on immunoblots (Western blot, dot blot) and in enzyme-linked immunosorbent assays (ELISA). The ready-to-use detection solution contains the AquaSpark® substrate and the oxidizing reagent hydrogen peroxide (H2O2).

Aldol® 518 alpha-D-galactopyranoside is a chromogenic and fluorogenic enzyme substrate used for detection of alpha-galactosidase activity.
