Specimens Dashboard
A critical component of PPMI is the standardized, longitudinal collection of biospecimens. These include plasma, serum, blood, cerebrospinal fluid (CSF), DNA and RNA, and peripheral mononuclear blood cells (PBMCs).
PPMI samples are available for request only for biomarker verification studies. Review an inventory of available PPMI biospecimens.

Academic and industry investigators can apply for use of PPMI biospecimens to verify potential PD progression biomarkers.
Specimen RequestResearch 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 Pre-Proposal.
