CELLINK A-RGD is one of our bioinks that has been optimized for enhanced cell adhesion. This bioink is based on the naturally derived polysaccharide, alginate that is isolated from the cell walls of brown algae. Alginate is a versatile biomaterial that has been utilized in diverse applications ranging from food to drug delivery. Alginates contain source dependent arrangement of (1-4)-linked-D-mannuronic acid (M units) and -L-guluronic acid (G units) monomers which comprise the alginate block polymer. The introduction of divalent cations such as Ca2+ bind G-units in adjacent chains together to rapidly form a gel. However, it is an improved blend of the CELLINK A as it contains covalently conjugated with an L-Arginine-Glycine-L-Aspartic Acid peptide sequence, also known as RGD. This peptide sequence is derived from fibronectin and is the most commonly recognized sequence by cells for adhesion. RGD has wide applicability in the engineering of nearly every tissue. The sequence has also been utilized for the surfacing of implants such as bone and vascular implants to improve integration within the body. Accelerate your research today with CELLINK A-RGD!
