In accordance with the Revolutionary Federal Acquisition Regulation (FAR) Overhaul (RFO) FAR 12.102 (a), the following documents the decision to restrict competition for this acquisition.

(1) Mission Area and Contracting Activity.

Requisition Number: 1162670

Requesting Activity Agency: USDA, ARS, Virus and Prion Research Unit

Contracting Activity: USDA, ARS, APD, Acquisition

(2) Brief Description of Supplies or Services We require an instrument and reagents that can directly mirror work done in a higher biosecurity laboratory that utilizes the 10X Genomics Chromium X instrument and library reagents for sequencing of single-cell mRNA libraries from agricultural species. In order for the work to be directly repeatable in a lower biosecurity level lab area, the same instrument and reagent technology is required.

(3) Suggested Source

10X GENOMICS, INC.

6230, STONERIDGE MALL ROAD

PLEASANTON, CA 94588 USA

(4) Justification for Restricting Competition and the Basis for that Decision.

A. Explain the unique qualifications/characteristics of the proposed contractor or product and why no other contractor or product/service can meet the Government's need.

There are other resellers of the consumables, but 10X Genomics is the sole manufacturer and seller of the ChromiumXO instrument as found in the market research conducted.

B. Describe market research conducted and the results or the reason why no market research was conducted.

Market Research Report done by the location showed only one known source. The Purchasing Agent (PA) searched the Internet for other sources without success. PA Reviewed previous purchases of similar/identical acquisitions and found that while other sources exist for the consumables, the equipment itself has only been sold by 10X Genomics. PA posted a Sources Sought notice on the GPE for any other interested sources with no results.
