ColMA Solution 5 mg/ml

ColMA is a unique variation of type I collagen that has been modified with photoactive methacrylate groups, enabling it to be crosslinked in the presence of a photoinitiator. ColMA Solution contains methacrylated collagen dissolved in the acidic Reconstitution Agent A. This biomaterial is a great starting point for your 3D cell culture research, whether you are bioprinting droplets or 3D constructs. Neutralize the solution, with the help of Collagen Buffer, and you are ready to print scaffolds for tissue engineering and high-throughput screening.

Recommended for use with BIO X, a temperature-controlled printhead and a heated printbed. Not recommended for use with INKREDIBLE+ or INKREDIBLE.
