General description
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.

Application
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.
Unit Definition
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.
