Applicazioni

1,9-Dimethyl-Methylene Blue zinc chloride double salt has been used for the quantification of sulfated glycosaminoglycans.[1]
DMMB is a cationic dye that specifically binds to sulfated glycosaminoglycans (sGAG) with an absorbance at ~525 nm.
DMMB is a cationic dye that specifically binds to sulfated glycosaminoglycans (sGAG) with an absorbance at ~525 nm. It has been used to quantitate glycosaminoglyans such as chondroitin sulfate, keratin sulfate, and heparan sulfate and sGAG chains in proteoglycans. One limitation to this method The sGAG-DMMB complex is unstable in solution and may precipitate. Precipitation of the complex was shown to improve stability.

The anti-osteoarthritic activity of the methanol fraction of deer bone oil extract (DBO-M) was evaluated in interleukin (IL)-1β-inflamed primary rabbit chondrocytes and in rats with monosodium iodoacetate (MIA)-induced osteoarthritis. The active compound in DBO-M was analyzed using a direct infusion

Biomaterials and, especially, scaffolds may function as temporary extracellular matrix (ECM), mimicking in vivo environmental structures and facilitating cell growth and tissue regeneration. ECM is composed mostly of glycosaminoglycans (GAGs) and proteins, the ratio of GAGs, hyaluronic acid (HA):sulphated GAGs
