Cultrex® Bovine Collagen I is purified from fetal bovine extensor tendons and is pepsin-treated to remove telopeptides. Collagen I is the major structural component of extracellular matrices (ECM) found in connective tissue and internal organs, but is most prevalent in the dermis, tendons, and bone. It is a 300 kDa molecule composed of two alpha1(I) chains and one alpha2(I) chain that spontaneously forms a triple helix scaffold at a neutral pH and 37̊ C. This phenomenon can be exploited to promote cell attachment, growth, differentiation, migration, and tissue morphogenesis during development. To provide the most standardized Collagen I, a special process is employed to provide material at a standard concentration of 1 mg/mL.

Cultrex® 5X Collagen I Solution is a purified stromal ECM protein that has been developed, produced and qualified for the Cultrex® Collagen I Cell Invasion Assays.

Quality control specifications:
