Irgacure 2959 Powder

2-Hydroxy-4′-(2-hydroxyethoxy)-2-methylpropiophenone (Irgacure 2959) is a photoinitiator utilized for the polymerization of water-soluble polymeric materials, such as hydrogels and bioinks. Irgacure 2959 has an absorption at 365 nm and can thus be used for photocuring bioinks. Photocuring is made easy by using the built in LED module of the BIO X and INKREDIBLE+ 3D bioprinting systems. The powder is non-sterile and therefore needs to be dissolved and sterile filtered before use in cellular applications.

Compatible with methacrylated biomaterials such as HAMA, GelMA and ColMA.
