CNP-NAG in the early diagnosis of renal injury

Various types of synthetic substrates have been reported for use in determinations of urinary N-acetyl-f3-D-glucosamiidase (EC 3.2.1.30; NAG) . To determine urinary NAG activity by a kinetic rate assay method, 2-chloro-4-nitrophenyl-N-acetyl-13-D-glucosaminide(CNP-NAG) is a new synthetic substrate. This method allowed good reproducibility in accordance with the reaction rate theory; required no specimen blank; was unaffected by endogenous components of urine such as glucose, ascorbic acid, and bilirubin; and could be adapted to various types of automated analyzers.

Principle
CNP-NAG, hydrolyzed by NAG , liberates the chromogen, CNP. NAG activity is determined by calculating the rate of CNP formation, in terms of the change in absorbance per minute at 400-405 nm.

Features
1)      Stability (both in powder and in solution)
2)      Operation simplification
3)      High sensitivity
4)      Good accuracy
