Blyscan™ GLYCOSAMINOGLYCAN Assay

The Blyscan™ Assay is a quantitative dye-binding method for the analysis of sulfated proteoglycans and glycosaminoglycans.

Sulfated glycosaminoglycan (sGAG) forms that can be measured; soluble salt extracts from:

  1. in vitro studies where extracellular matrix components are released by live cells into the cell culture medium;
  2. elastic, fibrous and hyaline cartilages;
  3. arteries, lung, skin and other material containing extracellular matrix (connective tissue);
  4. solid tumour specimens;
  5. cell and tissue extracts;
  6. aliquots from protein chromatography fractions
    Furthermore:
  7. sulfated glycosaminoglycans in amniotic fluid and urine samples can be measured;
  8. the assay may be adopted to detect and/or measure sulfated glycosaminoglycan degradative enzymes, and;
  9. the N- and O-sulfated glycosaminoglycan ratio can be measured
