Why is collagen used in the formation of RAFT™ Cultures?

The RAFT™ System uses type I collagen, the major component of natural extracellular matrix (ECM), as it is the ideal material for forming realistic 3D cell cultures. The patented RAFT™ Process enables a physiologically relevant concentration of collagen and overcomes the traditional problems when using collagen (e.g. lack of strength in the model, changes in construct size and shape caused by the cells) to produce strong, well-defined cell cultures.
