The collagen sponge is a collagen-based device developed for three-dimensional cell culture. The collagen porous sponge is prepared from an insoluble type I collagen isolated from bovine Achilles tendon. This sponge is natural bovine collagen (not atelocollagen). Cells will penetrate the sponge and proliferate in three-dimensions.
The collagen sponge (KKN-CS-35) is a disc shape of 32 mm in diameter and 1 mm thick.
