Description
GelMA is popular because it combines the biological properties of gelatin with the control of a synthetic material. It retains key cell-interaction features of gelatin while enabling stable hydrogel formation through light exposure. Once exposed to light, it forms a stable hydrogel that supports cell attachment, growth, and organisation.
It’s commonly used for:
- 3D cell culture and organoids
- Tissue engineering scaffolds
- 3D bioprinting
- Drug testing and disease models
Because the material can be tuned, it’s possible to create softer or stiffer environments depending on what your cells need. This allows the hydrogel to be adapted to different tissue types and experimental conditions.
Available options
We offer three standard GelMA formulations:
- GM-30 (Low methacrylation ~30%)
Softer gels that are easier for cells to spread and remodel. Often used for softer tissue models. - GM-60 (Medium methacrylation ~60%)
A balanced option with good printability and mechanical strength. Suitable for most general applications. - GM-90 (High methacrylation ~90%)
Stiffer gels that hold their shape well. Useful for 3D structures and applications where stability is important.
All variants are supplied as a white, sponge-like material with a molecular weight range of 100–200 kDa.
Performance
Our GelMA is designed to be consistent and easy to work with across different workflows.
- Stiffness can be tuned depending on the formulation
- Crosslinking is fast and reliable under light exposure
- Suitable for both extrusion and light-based bioprinting
- Supports high cell viability
Detailed characterisation data is available on request.
Custom options
We can also modify GelMA depending on your project, including:
- High porosity formulations
- Fluorescent GelMA
- Peptide-functionalised hydrogels
- Hybrid hydrogel systems
