NIH’s Office of the Director, Office of Acquisitions, intends to award a non-competitive firm-fixed-price purchase order to Integrated DNA Technologies, Inc. (Coralville, IA) for custom-designed ArcherDX VariantPlex NGS target-enrichment library preparation kits. IDT is the sole owner, manufacturer, and distributor of the proprietary ArcherDX VariantPlex AMP chemistry used by NHLBI’s Hematology Branch since 2019; the agency states this chemistry is required to maintain scientific continuity, prevent technical batch effects across longitudinal patient cohorts, and ensure compatibility with its established Archer Analysis bioinformatics pipeline. The acquisition is under NAICS 325413 (In-Vitro Diagnostic Substance Manufacturing), with a small-business size standard of 1,250 employees, and is not set aside for small business. The solicitation document and incorporated provisions and clauses are those in effect through Federal Acquisition Circular 2026-01, effective March 13, 2026. All responsible sources may submit a capability statement, proposal, or quotation for agency consideration.
