Rapid colorimetric assay for gentamicin injection

American Journal of Health-System Pharmacy, 1987
A rapid colorimetric method for determining gentamicin concentration in commercial preparations of gentamicin sulfate injection was developed. Methods currently available for measuring gentamicin concentration via its colored complex with cupric ions in alkaline solution were modified to reduce the time required for a single analysis.

Glycosyltransferase Activity Assay Using Colorimetric Methods

2019
The glycosyltransferases (GTs) are an important subclass of enzymes that catalyze the biosynthesis of glycosidic bonds in oligosaccharides, polysaccharides and glycoconjugates by transferring a sugar residue from a donor substrate to an acceptor substrate.

Colorimetric assay for chitinase

1988
Publisher Summary This chapter describes the colorimetric assay for chitinase, which is applicable to the various types of chitinase present in microorganisms, animals, and plants. The chapter evaluates it with particular reference to plant chitinases, because they may function as a defense against chitin-containing pathogens.

Colorimetric Assays of Na,K-ATPase

2016
The Na,K-ATPase is a plasma membrane enzyme that catalyzes active ion transport by the hydrolysis of ATP. Its activity in vivo is determined by many factors, particularly the concentration of intracellular sodium ions. It is the target of the cardiac glycoside class of drugs and of endogenous regulators.

A colorimetric assay for γ-glutamyltranspeptidase

Clinica Chimica Acta, 1971
A highly sensitive and simple colorimetric method for the assay of γ-glutamyltranspeptidase is described. As substrate, l-γ-glutamyl-p-nitroanilide has been used, which is dissolved with glycylglycine and MgCl2 in ammediol—HCl buffer. The enzyme splits the substrate in the γ-glutamyl group and p-nitroaniline, the γ-glutamyl group is bound by the ...
