Application

This is a low endotoxin GelMA for use in biomedical research applications.
GelMA can be used to form hydrogels for tissue engineering and 3D bioprinting. Gelatin methacryloyl (GelMA) is a polymerizable hydrogel material derived from natural extracellular matrix (ECM) components. Due to its low cost, abundance, and retention of natural cell binding motifs, gelatin has become a highly sought material for tissue engineering applications. The addition of photocrosslinkable methacrylamide functional groups in GelMA allows the synthesis of biocompatible, biodegradable, and non-immunogenic hydrogels that are stable in biologically relevant conditions and promote cell adhesion, spreading, and proliferation.

The cellular microenvironment plays an integral role in improving the function of microengineered tissues. Control of the microarchitecture in engineered tissues can be achieved through photopatterning of cell-laden hydrogels. However, despite high pattern fidelity of photopolymerizable hydrogels, many such materials

Gelatin has been commonly used as a delivery vehicle for various biomolecules for tissue engineering and regenerative medicine applications due to its simple fabrication methods, inherent electrostatic binding properties, and proteolytic degradability. Compared to traditional chemical cross-linking methods, such as
