Advanced BioMatrix offers PhotoHA, a methacrylated hyaluronic acid (HAMA) for photocrosslinkable hydrogels. These hydrogels provide native-like 3D HA gels with the unique attributes to be prepared at various concentrations and photocrosslinked to provide various gel stiffness. ThisPhotoHA product only contains the methacrylated hyaluronic acid. For the entire photocrosslinking kit, please visit aPhotoHAkit page. Hyaluronic acid is the most abundant glycosaminoglycan in the body being an important component of several tissues throughout the body. While it is abundant in extracellular matrices, hyaluronic acid also contributes to tissue hydrodynamics, movement and proliferation of cells, and participates in a number of cell surface receptor interactions. For the majority of cell types, it is recommended to add additional ECM proteins to the hyaluronic acid hydrogels. The proteins provide important cell binding sites.
