UNSPSC 51131664: Antithrombin

Antithrombin (AT) is a small protein molecule that inactivates several enzymes of the coagulation system. Antithrombin is a glycoprotein produced by the liver and consists of 432 amino acids. It contains three disulfide bonds and a total of four possible glycosylation sites.

UNSPSC 51131664 Antithrombin is a Commodity code that nominally covers anticoagulant pharmaceuticals used in clinical settings to prevent or treat thrombosis. However, the recent state and local procurement activity recorded under this code shows no alignment with the pharmaceutical scope — the single recent opportunity tagged to the code is a Sourcewell cooperative RFP for law enforcement equipment, which falls entirely outside the antithrombin product family. This mismatch suggests either a data-entry error in the state and local procurement system or that the code is not being used as intended for antithrombin procurement.

The one recent opportunity on record is Sourcewell RFP #061626, posted May 12, 2026, with a June 16, 2026 response deadline. Sourcewell, a State of Minnesota local government unit and service cooperative, issued the RFP on behalf of participating entities including Franklin, Grant, Grays Harbor, Chelan, and Yakima counties in Washington, with the resulting contract intended for use across thousands of governmental agencies, higher education institutions, K-12 school districts, nonprofit organizations, tribal governments, and public entities throughout the United States and Canada. The solicitation explicitly targets law enforcement equipment — a product category wholly unrelated to anticoagulant pharmaceuticals. Absent evidence of recent state and local solicitations for antithrombin under this code, the code shows little relevant recent activity for pharmaceutical procurement professionals.
