CELLINK GelMA
CELLINK gelatin methacrylate (GelMA) is a gelatin-based bioink that provides mammalian cells with the essential properties of their native environment. GelMA is modified with methacryloyl groups to crosslink with a photoinitiator (like LAP) or exposure to UV light (available using INKREDIBLE+, BIO X, and a 365 nm or 405 nm photocuring system). Available with a 0.25 percent LAP photoinitiator.
Available as lyophilized powder in our GelMA Kit for tailoring your own bioink formulation
Advanced formulations based off of CELLINK GelMA
Recommended for use with BIO X, a temperature-controlled printhead and a cooled printbed, or INKREDIBLE+ with a heated printhead. Not recommended for use with INKREDIBLE.
