LAP (Lithium Phenyl-2,4,6-trimethylbenzoylphosphinate) is a highly efficient, water-soluble photoinitiator ideal for visible light crosslinking of methacrylated hydrogels such as GelMA. It enables rapid and cytocompatible polymerization under mild conditions, making it perfectly suited for 3D cell culture, bioprinting, and tissue engineering applications. LAP supports tunable gelation kinetics and maintains high cell viability during encapsulation.

• Visible Light Activation – Enables rapid and efficient hydrogel photopolymerization under low-energy visible light, minimizing phototoxicity and preserving cell viability.
• Sterile & Ready to Use – Supplied as a lyophilized powder for easy, sterile reconstitution in aqueous solutions.
• Optimized for 3D Cell Culture – Delivers precise and tunable crosslinking of methacrylated biomaterials, supporting consistent results in 3D cell culture and biomedical research.
