This is a sole-source solicitation by the Eunice Kennedy Shriver National Institute of Child Health and Human Development (NICHD) for a one-year, firm-fixed-price comprehensive service agreement for a specific PacBio Sequel II or IIE sequencing instrument. The services, to be performed for the instrument located at the contractor's facility in Menlo Park, California, include parts, labor, consumables, and remote software support. The period of performance is from January 26, 2026, to January 25, 2027. The justification is that only PacBio Inc. can provide the necessary proprietary reagents, software, and specialized servicing for this sophisticated equipment. While this is not a request for competitive proposals, interested parties may identify their capability to provide the required services.
