Summary for Patent: 5,322,790
| Title: | Islet isolation process |
| Abstract: | A method of producing intact islets of Langerhans in an insulin producing condition uses a mixture of Hank\'s solution and 10% by volume fetal calf serum to ductally distend the human pancreas. The exocrine tissue of the pancreas is digested at about 37.degree. C. by an enzyme preparation of collagenase, trypsin and proteolytic enzyme present in the mixture at a level of about 0.2% by weight. The digestion is monitored at regular intervals during the process. The digested pancreas is comminuted, filtered and intact islets of Langerhans are recovered. The recovered islets retain their insulin producing properties. |
