Description

Sodium Hyaluronate GS-40 is based on a sodium hyaluronate fermented from Streptococcus zooepidemicus harvested and purified to an extreme degree of purity. The residual levels of endotoxins and proteins allows for use directly in vivo without need for any allergenic tests prior to administration. The product has a molecular weight in the 1,400,000 – 1,800,000 g/mol range (calculated from intrinsic viscosity data). Sold per gram, minimum order is 10 grams.

  • Intrinsic Viscosity [m3/kg] : 0.39 – 0.99
  • Appr. Mw [kDa] : 1,400,000 – 1,800,000 g/mol
  • Endotoxins [EU/mg]: ≤ 0.040
