This SOP defines a standardized method for packaging and cold shipping of research quality, fresh Non-Islet Pancreatic (Acinar) Tissue (NIPT) to approved investigators of human isolated islet preparations, for use in the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK) sponsored research in the Integrated Islet Distribution Program (IIDP). This protocol is written to assist the participating islet isolation centers and investigators who are part of this program.Note: This SOP was developed by the IIDP with assistance from Dagmar Klein, PhD, at University of Miami who has been working with acinar since 2011 when it became clear, as far as shipping and culture was concerned, that protease inhibitors must be used in the medium otherwise the tissue will digest itself.
