Laminin’s properties essential to cell differentiation, migration and adhesion are now available in a stable and easy-to-use bioink. You can use GelXA LAMININK 121 as a starting point for culturing many cell types. Laminin 121 is expressed during embryonic and early development stages of organ and tissue lining. This laminin variation is mostly found in the placenta, skeletal muscle and kidney tissue. GelXA LAMININK 121 is well-suited as a base material for culturing skeletal muscle, brain, kidney and liver cells.

GelXA LAMININK 121 is an enhanced formulation of our GelXA Bioink that contains several laminins and offers excellent printability and easy crosslinking, and is a great starting point for culturing many cell types in 3D. Also available with a CELLINK base.
