Each participant in the Repository contributed blood samples, from which we extracted DNA, serum, plasma, and PBMCs. We also collected and stored PAXgene tubes for supplying RNA. We did not collect CSF or other types of fluids or tissues. If you need access to samples or study participants that we currently can't provide, please contact our VP of Scientific Operations. We may be able to obtain what you need through a prospective collection, or help you find an alternative source.
