VitroINK Bioinks

Ready-to-use bioinks for 3D bioprinting.


VitroINK are ready-to-use, xeno-free (animal origin-free) bioink system either unmodified or modified with either RGD, Collagen-memetic, IKVAV, or YIGSR peptides or with Matrix Metalloproteinases (MMP) for biodegradable bioink. 


VitroINK is a family of the ready-to-use, xeno-free tunable bioink system that requires no UV,  no temperature/pH curing, or chemical cross-linking. The system is ready-to-use at room temperature, neutral in pH, transparent, and has excellent visibility after printing and cell culture. Due to the unique shear-thinning and rapid recovery mechanical property, VitroINK can maintain the printed structure without UV or other special curing methods. Adding cell culture medium after printing can further stabilize the printed structure and support cell growth. Cells can be pre-mix with VitroINK using the VitroINK Mixing Kit for mixing ratios at 3:1 or 10:1. Different versions of VitroINK may incorporate multiple biological functional ligands to promote cell attachment, cell-matrix interactions, cell proliferation, motility/migration and differentiation for many different applications.
