Glycosil is a thiol-modified hyaluronic acid. Glycosil hyaluronic acid is a component of the HyStem, HyStem-C and HyStem-HP hydrogel kits but can be purchased separately here. Comes with 10 mL of Buffer A. HyStem V2.0 kit components are reconstituted with a buffered 1X PBS. The resulting components will also result in a pH neutral isotonic salt hydrogel. The ending pH, osmo, and rheological properties are the same from Version 1.0 to Version 2.0. Glycosil hyaluronic acid is a component of the HyStem and Hystem-C hydrogel kits and can be purchased separately in individual vials. Glycosil is a thiol-modified hyaluronic acid and a constituent of native extracellular matrix (ECM). Glycosil is used in conjunction with Gelin-S or ECM proteins such as laminin, collagen, or fibronectin for most 3-D cell culture and tissue-engineering applications.
