Standard for the determination of NAG activity in urine research samples with the aid of the Test-Combination N-acetyl-β-D-glucosaminidase.
N-Acetyl-β-D-Glucosaminidase is a high molecular weight lysosomal enzyme existing as two isofomrs, Isoenzyme-A and Isoenzyme-B. It is present in human kidney. It has high molecular weight. It is highly active in renal proximal tubular cells. It has been reported that overexpressed urine-NAG reflects the proximal tubular dysfunction of the kidney.

The NAG standard is used for the determination of NAG activity in urine in life science research applications, with the aid of N-acetyl-β-D-glucosaminidase. It can be used in automatic analyzers.

Volume Activity: The activity of the NAG standard is approximately 20 mU N-acetyl-β-D-glucosaminidase from beef kidney per ml. For exact values, see data printed on the label.

Storage conditions (working solution): 2 to 8 ℃
Stability of the standard solution
The solution is stable for at least 1 month stored at 2 to 8 ℃, protected from light.

Preparation of the standard solution
Dissolve contents of one bottle with 3 ml double distilled water, close bottle and wait for 5 minutes. Dissolve contents completely by gentle swirling. Avoid creating foam.
