A critical component of PPMI is the standardized, longitudinal collection of biospecimens, which include plasma, serum, blood, cerebrospinal fluid (CSF), DNA and RNA. An inventory of the biospecimens is available through the PPMI database and can reviewed by investigators interested in incorporating PPMI samples in their research. Please note that PPMI samples can only be used for biomarker verification studies.
Application Process to Request Specimens
Researchers interested in requesting specimens are encouraged to review the Process for Requesting Specimens. Researchers requesting specimens must agree to the Biospecimen Use Agreement and the Publications Policy.

Research Funding for Specimen Studies
Researchers requesting biospecimens may also apply for funding from The Michael J. Fox Foundation (MJFF). The review processes for PPMI biospecimen access and MJFF funding of research are separate processes; approval for use of PPMI biospecimens does not guarantee MJFF funding. MJFF has identified Biomarkers as a priority funding area and will consider proposals from researchers who have been granted PPMI samples. Investigators interested in requesting funding from MJFF should indicate that in their Letter of Intent.
Ongoing Specimen Analyses and Other Resources
A listing of preliminary analyses specified by the Steering Committee and performed by PPMI cores, as well as analyses performed by additional investigators will be listed in the Ongoing Analyses section of this site (expected to be live Spring 2011). Investigators who are granted samples from PPMI agree to update this information annually, providing the research public with a comprehensive list of the latest findings coming out of PPMI.
