  • Providing sub-optimal conditions for proteases such as collagenase may assist in protecting the collagen compositions from degradation.
  • Suboptimal conditions for proteases may be achieved by formulating the compositions to eliminate or limit the amount of calcium and zinc ions available in solution. Many proteases are active in the presence of calcium and zinc ions and lose much of their activity in calcium and zinc ion free environments.
