Opis ogólny

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.[1] 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.[2]

Zastosowanie

N-acetyl-β-D-glucosaminidase (NAG) has been used for preparing standards for the determination of N-acetyl-β-D-glucosaminidase in urine[1] in life-science research applications.

Uwaga dotycząca przygotowania

Working solution: Preparation of solutions:
  1. Buffer solution
    Dissolve the contents of bottle 1 with 55 ml double-distilledwater.
  2. Substrate solution
    Dissolve the contents of bottle 2 with 55 ml solution I.
  3. Stop reagent
    Dissolve the contents of bottle 3 with 110 ml double-distilled water.

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.

Przechowywanie i stabilność

Keep container tightly closed in a dry and well-ventilated place.
