PhotoGel 50% DS (GelMA) is a freeze-dried product of porcine gelatin functionalized with methacrylate groups. It is one of the most popular biomaterials in tissue engineering, 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. 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.
