High-purity gelatin methacryloyl (GelMA) hydrogel optimised for 3D bioprinting and spheroid culture. Tunable via visible light crosslinking, GelMA supports reproducible fabrication of physiologically relevant in vitro models with excellent biocompatibility and mechanical control. GelMA is a photocrosslinkable extracellular matrix designed for advanced 3D cell culture and bioprinting applications. Synthesized from pharmaceutical-grade raw material functionalized with a high degree of methacrylation, it enables robust cell encapsulation and precise mechanical tuning using cytocompatible visible light (405nm) crosslinking.

Its rheological properties and low batch-to-batch variability make it particularly well-suited for extrusion-based printing, as well as for creating 3D spheroid models with epithelial, mesenchymal, or endothelial cells. GelMA’s native bioactivity, combined with its tunability and compatibility with automated workflows, makes it a versatile platform for disease modeling, drug screening, and tissue engineering.

• Highly tunable – precisely control stiffness, porosity, and degradation for application-specific needs
• Supports cell viability and function – provides a biologically relevant microenvironment for cell attachment, proliferation, and differentiation
• Compatible with 3D bioprinting – use alone or blend with other biomaterials to create a customised extracellular matrix (ECM) for biofabrication and tissue engineering
