title: Cross-linking of collagen by ascorbate-copper ion systems.
abstract: Cross-linking occurred rapidly in collagen when it was treated with ascorbate-copper ion systems. Sodium dodecyl sulfate-polyacrylamide gel electrophoretic patterns of CNBr peptides suggest that in some respects the modifications by the ascorbate-copper ion systems mimicked those that occurred in collagen with aging.
