Product Features
The assay is ready-to-use for manual methods and adaptable for analyzers. The assay is specific for NAG and has no detectable reaction with other glycosidases and has excellent sensitivity with a linear range from up to 200 U/L and excellent precision (CV <5%) . There is no significant interference from hemoglobin or albumin. Interference from bilirubin occurs only at levels higher than 5 mg/dL. The reagent is stable for 12 months from date of manufacture when stored at @ 2°-8°C.



Assay Principle
The Diazyme NAG assay uses a specific substrate, 2-methoxy-4-(2’nitrovinyl)-phenyl 2-acetamido-2-deoxy-β-D-glucopyranoside (MNP-GlcNAc) that is hydrolyzed by NAG to produce 2-methoxy-4-(2’-nitrovinyl)-phenol product. The product formation is detected at 505 nm upon addition of an alkaline buffer.



Intended use
The N-acetyl-β-D-glucosaminidase (NAG) assay kit is for the quantitative in vitro determination of NAG in patient urine samples. The assay is for investigational use or export only.
