Based on our GelXA Bioink, GelXA FIBRIN contains fibrinogen to help you study wound-healing environments. Fibrinogen forms complex and stable networks after crosslinking. The included crosslinking solution contains thrombin to develop a compound network with unparalleled stability. GelXA offers dual-crosslinking capabilities through photocuring and treatment with our ionic thombin-containing crosslinking agent.

Also available with a CELLINK base.





Available in 3 mL cartridges.
Includes one bottle of crosslinking agent and one vial of thrombin.
