Cultrex® Rat Collagen I, Lower Viscosity is purified from rat tail tendons and is provided at a standard concentration that is lower in viscosity, making it easier to work with. 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 37°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 approximately 3 mg/ml.

Cultrex® Rat Collagen I, Lower Viscosity is a purified stromal ECM protein that has been developed, produced and qualified at a low viscosity for general cell culture applications.

Quality control specifications:
