Protocols & MSDSs

Extralink™

Extralink is polyethylene diacrylate (PEGDA) with a molecular weight of 3400 Da. It is a thiol-reactive crosslinker that convalently reacts with the thiol groups in Glycosil™, Heprasil™ and Gelin-S™ to form viscoelastic hydrogels¹.

Gelation

Extralink is used to chemically crosslink Glycosil, Heprasil and Gelin-S. 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.

Volume

Extralink vials come in two sizes:

1. 0.5 mL
2. 2.5 mL
