PhotoCol® is a purified methacrylated type I bovine collagen. PhotoCol® provides native-like 3D collagen gels with the unique attributes to be prepared at various concentrations and crosslinked to provide various gel stiffness.
Methacrylated type I collagen is produced from telo-peptide intact bovine collagen where the collagen has been modified by reacting the free amines, primarily the ε-amines groups of the lysine residues as well as the a-amines groups on the N-termini. Over 20% of the total lysine residues of the collagen molecule have been methacrylated. The collagen is extracted from bovine hide and contains a high monomer content.
