Product Description: PeptiInk® Alpha 4 PLUS™ is a ready-to-use fully synthetic positively charged peptide bioink functionalized with fibronectin (RGD) and collagen (GFOGER) motifs, mimicking the extracellular matrix more closely and encouraging better cellular adhesion. PeptiInk® Alpha 4 PLUS™ is suitable for the culture of a wide variety of cells, including primary cells, immortalized cell lines and stem cells.PeptiInk® Alpha 4 PLUS™ is highly consistent in mechanical stiffness (G’) and pore size, resulting in excellent reproducible results. Hence, PeptiInk® Alpha 4 PLUS™ can be used for both in vitro and in vivo applications with physiologically and clinically relevant results.
