Description

PhotoGel 50% DS is lyophilized GelMA (gelatin methacrylate). It’s a freeze-dried product of porcine gelatin functionalized with methacrylate groups. GelMA is one of the most popular biomaterials in tissue engineering as it can be used in a variety of applications.

PhotoGel 50% DS is easy to dissolve in our Reconstitution Agent P at your target concentration to prepare your unique bioink. The addition of a photoinitiator is vital to make your bioink photocrosslinkable and thereby stable in cell culture applications.

Recommended for use with BIO X, a temperature-controlled printhead and a cooled print bed, or INKREDIBLE+ with a heated printhead, as well as BIONOVA X.
