Porcine gelatin (heat-denatured collagen) was digested with a bioreactor using an enzyme-coupled matrix (ECM) with purified collagenase. The digested gelatin, FreAlagin type R (M.W. range 200-10000 Da), was further purified by an HPLC system depending upon molecular size. The molecular weight range of the purified fractions, FreAlagin type P and type AD,(More)
Peptides produced by the enzymatic degradation of collagens are reported to have various activities of biological and medical interest. The mechanisms underlying their actions are, however, poorly understood. We have produced, by collagenase digestion of type I collagen, a highly purified, non-antigenic, and low allergenic tripeptide fraction (collagen(More)
