Used in biomedical research to quantify levels of galactose-6-sulfate in biological samples, aiding in the study of lysosomal storage disorders such as mucopolysaccharidosis. Enables researchers to assess enzyme activity and substrate accumulation in cell cultures, tissue extracts, or serum samples. Commonly applied in preclinical studies to evaluate therapeutic interventions, including enzyme replacement therapies and gene treatments. Supports immunoassay-based detection with high sensitivity and specificity, facilitating accurate measurement in mouse models.
