biomaterial for tissue engineering and 3D printing applications
Type I collagen is one of the main structural proteins found in extracellular matrix (ECM) and connective tissue. Collagen is found in over 30% of total body protein, making it an excellent biomaterial for tissue engineering and 3D printing applications. Collagen forms fibrous networks in the body, enhancing the structural integrity of the ECM while promoting cell adhesion, growth, biological signaling and tissue morphogenesis.

The collagen series
We developed the Collagen Series using type I collagen (Coll 1) and collagen methacrylate (ColMA) variations designed for applications in 3D cell culture, surface coating for regenerative medicine and many more. CELLINK leverages collagen’s unique native physiological properties in an innovative formula to propel research further. We source collagen from high-quality rat tail tendons to provide pure and sterile Coll 1 and ColMA.
We offer collagen as a reconstituted solution and freeze-dried powder, enabling you to customize your biomaterial formulations and create printable hydrogels, supplemented cell culture coatings and 3D cell culture matrices.
rheological properties and crosslinking capability
We pay great attention to the rheological properties and crosslinking capability of our collagen-based biomaterials because they are integral to the success of your research. You can use the CELLINK Collagen Series in multiple ways. Coll 1 can be printed as a 3D cell culture model between 15 and 25 degrees, and thermally gelated at 37 degrees Celsius. Rapid gelation occurs within a few minutes with the highest storage modulus increase for the highest concentration of Coll 1. ColMA is a unique variation of type I collagen that has been modified with photoactive methacrylate groups, enabling it to be crosslinked with light at 365- and 405-nm wavelengths.
