Általános leírás
N-acetyl-β-D-glucosaminidase (NAG) is mainly used in the colorimetric assay for the determination of N-acetyl-β-D-glucosaminidase in urine. NAG hydrolyzes 3-cresolsulfonphthaleinyl-N-acetyl-D-glucosaminide to release 3-cresolsulfonphthalein, which is measured photometrically at 580nm. It is an intracellular lysosomal enzyme, present in the S3 segment of proximal tubular cells and distal nephron. Presence of NAG in the urine shows an organelle impairment in proximal tubule. Level of NAG rises in individuals over 70 years of age.
Alkalmazás
N-acetyl-β-D-glucosaminidase (NAG) has been used for preparing standards for the determination of N-acetyl-β-D-glucosaminidase in urine in life-science research applications.

Elkészítési megjegyzés
Working solution: Preparation of solutions:
Storage conditions (working solution): Stability of solutions:
Solution II is stable for 1 month when stored at 2 to 8 °C, protected from light.
Solution III is stable for 1 month stored at 2 to 8 °C.
Stability of the sample:
The activity determination of the N-acetyl-β-D-glucosaminidase (NAG) should be carried out directly after collecting the sample. Turbid urines should be centrifuged and the supernatant decanted. NAG is stable for one week at 2 to 8 °C and for one month when stored at -15 to -25 °C.
- Buffer solution
Dissolve the contents of bottle 1 with 55 ml double-distilledwater. - Substrate solution
Dissolve the contents of bottle 2 with 55 ml solution I. - Stop reagent
Dissolve the contents of bottle 3 with 110 ml double-distilled water.

Chronic heart failure may lead to chronic kidney disease. Previous studies suggest tubular markers N-acetyl-b-D-glucosaminidase (NAG) and Kidney-injury-molecule-1 (KIM-1) as potential markers for the cardiorenal syndrome (CRS). The prognostic value of NAG and KIM-1 regarding implantable cardioverter defibrillator (ICD) shock
