CELLINK GelMA inks are derived from porcine gelatin and enhanced through the incorporation of methacrylate groups to facilitate their crosslinking. Compared to non-modified gelatin, gelatin methacryloyl retains its shape at physiological temperature and conditions. CELLINK GelMA bionks are shear thinning and have excellent printability through a wide range of nozzle diameters with an unparalleled ability to form filaments at low pressures. Available as both sterile powders or ready to print formulations. Ask today for a free sample!

Printability Data

Conical tip (~23.4° C)

This diagram shows the printability and properties of CELLINK GelMA, printed with a 27G conical tip at room temperature (around 23.4° C). The different lines correspond to different printing pressures as indicated by the colors in the legend.


Representative diameters of CELLINK GelMA printed at 20 kPa and increasing translation rates through a 27 G nozzle, representing filaments of CELLINK GelMA at translation rates of (a) 500, (b) 800, (c) 1100, (d) 1400, (e) 1700, (f) 2000 mm/min.



GelMA A is a result of a unique blend of GelMA and alginate, which provides the most advantageous gelatin-based bioink in the world. This blend exhibits unparalleled printability at room temperature with a minimal risk for nozzle clogging, even in bioprinting systems with no thermal control. Crosslinking is possible through either the UV activation of the photoinitiator or through the addition of our ionic crosslinking solution, which allows tuning the mechanical properties of printed constructs for the best match with desired engineered tissues.


GelMA C is a special blend of GelMA and nanofibrillar cellulose, which takes advantage of the best features of both components. This blend exhibits smooth printability at room temperature without a thermal control, and also provides fibrillar morphology benefiting certain cell types. GelMA C is quickly crosslinked through the UV activation of a photoinitiator or through the addition of our ionic crosslinking solution. The ink retains its shear thinning properties at physiological conditions exhibiting excellent printability through a wide range of nozzle diameters and at low extrusion pressures.


The GelMA HA has been formulated to incorporate methacrylate hyaluronic acid into our globally known GelMA products. Hyaluronic acid plays an important role in a wide variety of different tissues such as skin, cartilage, bone, and nerves. The research possibilities are immense.


Our GelMA is now available in syringes as a ready-to-use reconstituted formulation at physiological pH and osmolarity without a photoinitiator. Quickly tailor your own GelMA bioink or 3D cell culture composition by simply diluting our high concentration buffered GelMA solution with a photoinitiator or other additives. Warm it up, mix well, and deliver results. GelMA preparation has never been quicker.
