HyStem®-IRG UV QuickSet Kit


The HyStem®-IRG QuickSet Kits contain UV-crosslinkable hyaluronic acid that facilitates 3D cell culture for tissue engineering and small-scale bioprinting applications.

Glycosil® (thiol-modified hyaluronic acid), Gelin-S® (thiol-modified gelatin), PEGCure (PEG-norbornene), and Irgacure 2959 Photoinitiator for photoinitiation are the components of the HyStem-IRG QuickSet Kit.

After being combined and exposed to UV light (365 nm), the contents form a transparent hydrogel. All vials are packaged as sterile, vacuum-sealed, lyophilized solids that are covered in argon and kept at a low temperature.

The HyStem®-IRG QuickSet Kit, one of the original hyaluronic acid-based light-controlled hydrogels, supports 3D cell culture for use in tissue engineering and small-scale bioprinting applications.

For micro-scale bioprinting, the HyStem®-IRG QuickSet Kit offers improved temporal and spatial control. In contrast to other hydrogel formulations, when exposed to ultraviolet light, gelation happens within 30–60 seconds as opposed to 30 minutes.


  • Optimized for micro-scale bioprinting applications
  • Maintains standard characteristics of other HyStem hydrogels
  • Enables faster, flexible gelation times
  • Controlled by UV light


  • HyStem® (thiol-modified hyaluronic acid), Gelin-S® (thiol-modified gelatin), UVlink™ (PEG-norbornene), Irgacure 2959 for photoinitiation, and DG water make up the HyStem® UV QuickSet kit
  • After mixing the ingredients and exposing them to UV light, a transparent hydrogel is created
  • All vials are packaged as solid lyophilized sterile materials that are slightly vacuumed and covered in argon
