Used in biomedical research to quantify levels of glucosamine-6-sulfate in biological samples such as cell lysates, tissue extracts, and bodily fluids. This ELISA kit enables researchers to study the role of GNS in glycosaminoglycan metabolism, particularly in the biosynthesis of heparan sulfate, which is involved in cellular signaling, inflammation, and pathogen interactions. It is widely applied in studies related to lysosomal storage disorders, especially those involving sulfatase enzyme deficiencies like Sanfilippo syndrome. The assay supports drug development and evaluation of therapeutic strategies targeting metabolic correction or enzyme replacement. Its high sensitivity and specificity make it suitable for monitoring changes in GNS concentrations under experimental conditions in both preclinical and clinical research settings.
