The PhotoHA Soft kit consists of purified methacrylated hyaluronic acid and an Irgacure photoinitiator. PhotoHA is 100 mg of lyophilized methacrylated hyaluronic acid (GM-HA). The photoinitiator consists of Irgacure 2959 to be formulated in methanol (methanol not included) which allows UV crosslinking of the gelatin at 365 nm. PhotoHA provides 3D hyaluronic acid hydrogels with the unique attributes to be prepared at various concentrations and photocrosslinked to provide various gel stiffness. GM-HA forms softer hydrogels than HAMA. 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. 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.
