The NIDDK Integrated Islet Distribution Program (IIDP) is seeking Requests for Proposals (RFP) for Affiliated Islet Isolation Centers (IICs). 

The continuing mission of the IIDP is to provide the scientific community with critical human islet resources for diabetes research. The IIDP facilitates the distribution of human islets to biomedical researchers by establishing partnerships with qualified islet isolation facilities that prepare and distribute human islets. The program manages an application process to establish investigator eligibility to receive islet shipments, informs investigators of islet availability, manages a cost recovery system through fees collected from islet recipients, and oversees standardized phenotypic and genotypic analyses of islet preparations distributed throughout the IIDP network. 

The purpose of this RFP is to identify and evaluate expert human IICs that can provide the highest quality human isolated islets and related tissues to the IIDP in a dependable, consistent, cost-effective manner.

IICs are hereby invited to submit an application in response to this Request for Proposals to become an IIDP IIC. The IIC should be led by an experienced investigator with a solid track record of providing resources and services to the diabetes research community, and should have proficiency in procuring and processing human islets for research use.
