Notes
N-Acetylglucosaminidase (beta-NAG) Activity Assay Kit (Colorimetric) (ab204705) provides a simple and sensitive method for monitoring NAG enzymatic activity. In this assay, NAG uses a synthetic p-nitrophenol derivative (R-pNP) as a NAG substrate and releases pNP which can be measured at absorbance (OD 400 nm). The assay can detect as low as 50 μU of NAG activity in a variety of samples.
beta-NAG assay protocol summary:
- add samples and standards to wells
- add NAG substrate and incubate for 5-30 min
- add stop solution and incubate for 10 min
- analyze with microplate reader
This product is manufactured by BioVision, an Abcam company and was previously called K733 β-N-Acetylglucosaminidase Activity Assay Kit (Colorimetric). K733-100 is the same size as the 100 test size of ab204705.
β-N-Acetylglucosaminidase (NAG, EC 3.2.1.52) is a lysosomal enzyme that is expressed in various tissues, including kidney, liver and lungs. NAG can cleave N-acetyl-glucosamine, a monosaccharide derivative of glucose. Its concentration in urine is minimal due to its inability to cross the glomerular basal membrane. Increased concentration of NAG in urine indicates renal tubular cell breakdown. Acute Kidney Injury (AKI) is the sudden loss of kidney functions, causing electrolyte imbalance, and retention of urea and other nitrogenous products. NAG has become one of the most studied and used biomarkers for the detection and diagnosis of AKI.
Supplementary info

- Activity summary
N-Acetylglucosaminidase also known as NAG β-NAG and NAG-5 plays an important role in the breakdown of glycoproteins by catalyzing the hydrolysis of terminal N-acetylglucosamine residues in N-acetyl-β-D-glucosaminides. This enzyme has a molecular mass of approximately 55 kDa. It expresses in various tissues with noticeable activity in lysosomes and is critical for maintaining cellular homeostasis by processing glycosylated proteins.
- Biological function summary
The enzyme N-acetylglucosaminidase is essential for cell growth signaling and structural integrity. It belongs to a larger group known as glycoside hydrolases which cooperate during the degradation of complex carbohydrates and glycoproteins. NAG's function impacts the lysosomal degradation pathway where it often works with substrates like glycosaminoglycans ensuring the recycling of cellular components in the lysosomal environment.
- Pathways
N-acetylglucosaminidase integrates with lysosomal storage pathways and takes part in glycosaminoglycan degradation. Its activity is keenly tied with proteins such as β-glucuronidase working alongside in the sequential breakdown of glycan chains. These pathways are important for cellular waste disposal and recycling contributing to overall metabolic harmony in cells.
- Associated diseases and disorders
N-acetylglucosaminidase links to conditions such as mucopolysaccharidosis and Tay-Sachs disease. Deficiency in NAG enzymatic function leads to improper degradation of glycosaminoglycans or gangliosides contributing to their pathophysiology. The enzyme shares this relation with proteins like Hexosaminidase A in Tay-Sachs disease demonstrating its pivotal role in neurological health.
