ABSTRACT:
Advanced islet separation technology incorporates an automated method, automated control methodology, process control interface, and automated apparatus to separate (isolate) and process pancreatic islets in a tissue suspension in physiologic process solution, utilizing microprocessor control and/or microprocessor computer control and software programming (code) to interface and control the process temperature, fluid flow rate, pH, dissolved oxygen concentration, endotoxin concentration, dissolved nitric oxide concentration, nitric oxide synthase activity, proteolytic enzyme activity, and/or pressure of the islet containing physiologic process solution, the extent of islet separation, including real-time data acquisition and recording of process variables.
