In the past month you may have noticed that the identifying number associated with the islets you are receiving seems a little longer - not the normal 4 letters followed by three numbers that most researchers came to identify as the UNOS number, representing the donor from whom the pancreas and the isolated islets came. The new label beginning with “RRID:SAMN” followed by 8 numbers is an automated tag called a Research Resource Identifier (RRID). This identifier is generated in collaboration with the National Center for Biotechnology Information (NCBI) and dkNET, through which RRID metadata is catalogued and tracked. IIDP has generated this identifier for every one of their islet preparations, in order to cooperate with the National Institute of Health (NIH) mandates for Rigor and Reproducibility.
