Abstract: Collagen, available from domestic animals, is freed of noncollagen proteins, glycosaminoglycans and lipids by enzymatic treatment with a proteolytic enzyme to yield a product which is soluble in dilute acidic aqueous solutions (collagen in solution--CIS). The naturally occurring collagen is modified by removal of certain terminal peptide chains, which are described as telopeptides. The modified collagen, so derived, is described as atelopeptide collagen. Native collagen is immunogenic, while atelopeptide collagen is nonimmunogenic or possessed of a negligibly low level of immunogenicity.The collagen in solution is then treated according to a specific regimen under conditions whereby the collagen slowly separates from solution while exposed to mild shear forces. This procedure results in the formation of a fibrous precipitate composed of regularly ordered fibers of collagen possessed of a ropelike structure. These resulting aggregates are referred to as native fibrous micropolymers (NFM).
