Advanced BioMatrix offers PhotoGel, a purified methacrylated gelatin kit for photocrosslinkable hydrogels. PhotoGel provides 3D tunable gels with the unique attributes to be prepared at various concentrations and crosslinked to provide various gel stiffness. The PhotoGel consists of purified methacrylated porcine gelatin (1 gram). The gelatin is type A 300 bloom. PhotoGel is produced from methacrylated gelatin where the gelatin has been modified by reacting the free amines, primarily the e-amines groups of the lysine residues as well as the a-amines groups on the N-termini. >75% of the total lysine residues of the gelatin molecule have been methacrylated. The individual product only contains the methacrylated gelatin.
