Extralink® is polyethylene diacrylate (PEGDA) with a molecular weight of 3500 Da. It is a thiol-reactive crosslinker that covalently reacts with the thiol groups in Glycosil®, and Gelin-S® to form viscoelastic hydrogels. Extralink® vials are >80% acrylated and supplied as the crosslinking component in all HyStem® hydrogel kits.

Extralink® is used to chemically cross-link Glycosil®. The gelation time ranges from as short as 5 minutes to as long as a couple of hours, depending upon the amount of Extralink used and the concentration/dilution of the Glycosil®, and/or Gelin-S.
