Extralink® (PEGDA, polyethylene glycol diacrylate) 5 x 2.5mL vials of diacrylated PEG . Vials are blanketed by nitrogen and under a slight vacuum.
Extralink® is polyethylene diacrylate (PEGDA) with a molecular weight of 3500 Da. It is a thiol-reactive crosslinker that convalently reacts with the thiol groups in Glycosil®, Heprasil® and Gelin-S® to form viscoelastic hydrogels. Extralink® vials are >80% acrylated and supplied as the crosslinking component in all HyStem® hydrogel kits.
Extralink® vials are paired with HyStem-C and HyStem–HP kits while Extralink-Lite vials are paired with HyStem hydrogel kits to provide comparable experiences despite the different HA concentrations.
Extralink® is used to chemically crosslink Glycosil (or Heprasil) and Gelin-S in Hystem-C and HyStem-HP kits. 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, Gelin-S and/or Heprasil.
Similarly, Extralink-Lite is used in place of Extralink for applications where Gelin-S is not included. The higher relative concentration of Glycosil requires less crosslinker to emulate the gelation time and stiffness of HyStem-C and HyStem-HP.
