About this file
This is a Decision to Restrict Competition under the Simplified Acquisition Threshold document issued by the United States Department of Agriculture.
The USDA APHIS Veterinary Services (requesting activity in Ames, Iowa) seeks to procure a Luminex 200 system with xPONENT software (RUO part numbers LX200-XPON-RUO, 64-00146-00-001, and 64-10099-00-001) through the USDA APHIS MRPBS AAMD contracting office in Minneapolis, Minnesota (Requisition Number 1165775). The Luminex 200 is a bead-based multiplex analyzer used to serotype salmonella, capable of measuring up to 100 analytes in a single sample while delivering reproducible, high-quality results from minimal sample volumes through xMap technology and xPONENT software integration.
Competition has been restricted to sole source procurement from Luminex Corporation (12212 Technology Blvd, Austin, TX 78727) based on unique qualifications exclusive to their product. The justification centers on Luminex's proprietary xMAP technology, which is the only reagent compatible with the required methodology. This technology was specifically developed to complement classical Salmonella serotyping according to the White-Kauffmann-LeMinor Scheme, the globally accepted standard for serotyping Salmonella bacteria based on surface antigen patterns. The contracting officer notes that market research confirmed no comparable serotyping systems from other vendors met the required compatibility and performance criteria. The justification was certified by Tonyia Mackie, Microbiologist, and approved by Contracting Officer Kathy Melby on July 22, 2026.
