PeptiInk® Alpha 4™
Synthetic Self-Assembling Peptide Bioinks
PeptiInks® are specifically designed peptide hydrogels for liquid handling and 3D bioprinting cell culture applications. The PeptiInk® family of bioinks are shear thinning and can be used for 3D bioprinting with any extrusion-based printer. Cells can be encapsulated and printed directly with structural definition and long-term viability and stability.
PeptiInks® are linked to the PeptiGel® series, allowing you to continue using the most suitable product (e.g. Alpha 4) for your cells when you transition from bench to printed 3D cell culture.
PeptiInk® Alpha 4™ is a ready-to-use fully synthetic positively charged peptide bioink. PeptiInk® Alpha 4™ is biologically relevant, mimics the extracellular matrix and is suitable for the culture of a variety of cells, including primary cells, immortalized cell lines and stem cells.
PeptiInk® Alpha 4™ is highly consistent in mechanical stiffness (G’) and pore size, resulting in excellent reproducible results. Hence, PeptiInk® Alpha 4™ can be used for both in vitro and in vivo applications with physiologically and clinically relevant results.
Value Starter Pack
When beginning to work with PeptiGels®, we recommend purchasing our Value Starter Pack. This includes PeptiGel® to test with your cells to enable you to identify the most suitable matrix environment. The Pack also includes a Gilson positive displacement pipette (various sizes are available), a box of sterile tips and a pack of Greiner Thincerts. Contact us for additional information.
PeptiInk® supports complex structures laden with cells
PeptiInk® successfully prints complex structures laden with mammalian epithelial cells using a commercially available extrusion bioprinter. Structures could be printed with high structural integrity and geometrical/dimensional accuracy. After 7 day culture, the number of viable cells remained high and began to proliferate.
