The National Institutes of Health intends to award a non-competitive, firm-fixed-price purchase order to Brigham and Women’s Hospital (BWH) in Somerville, Massachusetts, for a 3-month service to retrieve, process, and ship previously collected blood samples to the NIA Laboratory of Neurogenetics. The work involves retrieving 821 stored blood samples from the BWH Biorepository, aliquoting white blood cells, preparing quality control samples, and packaging and shipping them in compliance with regulations. This is a follow-on effort to an existing sleep health study, and only BWH can provide the required services as the samples are stored at their facility. The period of performance is from June 1, 2026, through August 1, 2026. No budget amount is specified in the description.
