  • The Blyscan Assay is a quantitative dye-binding method for the analysis of sulfated proteoglycans and glycosaminoglycans, (sGAG).
  • Test material can be assayed directly when present in a soluble form, or following papain extraction from biological materials. The assay can be used to measure the total sGAG content and can also be adopted to determine the O- and N-sulfated glycosaminoglycan ratio within test samples.
  • The dye label used in the assay is 1, 9-dimethylmethylene blue and the dye is employed under conditions that provide a specific label for the sulfated polysaccharide component of proteoglycans or the protein free sulfated glycosaminoglycan chains.
  • The assay is not suitable for small sulfated disaccharide fragments or for samples containing alginates, as these contain uronic acid.
  • Time required is 1 hour.
  • Manufactured by Biocolor.
