CELLINK Bioink is the first universal bioink designed to print human tissue models with any 3D-bioprinting system, commercially available or developed in-house. CELLINK Bioink is a non-animal derived polysaccharide hydrogel that is ideal for 3D bioprinting and cell culturing. CELLINK Bioink is composed of alginate and highly hydrated cellulose nanofibrils with morphological similarity to collagen, providing mammalian cells with a milieu that resembles their natural matrix. Its excellent printability enables you to bioprint complex, cell-laden tissue constructs, such as a human auricle. The unique biocompatibility and printability of CELLINK Bioink offer outstanding results that will take your research to the next level! Use our CELLMIXER to mix CELLINK Bioink with a high concentration of cells and  a one-step bioprinting process. After bioprinting, CELLINK Bioink crosslinks easily with the included ionic crosslinking agent.
