5-Bromo-4-chloro-3-indolyl-beta-D-glucuronide cyclohexylammonium salt CAS:18656-96-7
5-Bromo-4-chloro-3-indolyl-beta-D-glucuronide cyclohexylammonium salt, also known as X-glucuronide, is a chemical compound commonly used in molecular biology and enzymology experiments. It is a chromogenic substrate that is often utilized to detect the activity of the enzyme beta-D-glucuronidase.
The compound consists of an indole group coupled to a glucuronic acid moiety through a glycosidic bond. The bromo and chloro substituents provide stability and enhance the solubility of the compound.
When incubated with a sample containing beta-D-glucuronidase, the enzyme cleaves the glycosidic bond, releasing the indole moiety. This reaction results in the formation of a blue precipitate or color change, allowing for easy visual or spectrophotometric detection of the enzyme activity.
Due to its specificity for beta-D-glucuronidase, X-glucuronide is widely used in molecular biology techniques such as bacterial and yeast transformation assays, reporter gene assays, and histochemical staining. It provides a convenient and sensitive means to detect the presence or expression of beta-D-glucuronidase and is often employed in conjunction with other genetic or biochemical assays.

GABA (Gamma aminobutyric acid) CAS:56-12-2 Manufacturer Supplier
Gamma aminobutyric acid (GABA) is the chief inhibitory neurotransmitter in the mammalian central nervous system. It plays a role in regulating neuronal excitability throughout the nervous system. In humans, GABA is also directly responsible for the regulation of muscle tone. Although chemically it is an amino acid, GABA is rarely referred to as such in the scientific or medical communities, because the term “amino acid,” used without a qualifier, conventionally refers to the alpha amino acids, which GABA is not, nor is it ever incorporated into a protein.
