UNSPSC 41106500: Protein expression products

UNSPSC 41106500 Protein expression products is a Class code that encompasses specialized research and laboratory equipment, reagents, and supplies used in life sciences and analytical research environments — not the protein production materials the code name suggests. State and local governments procure under this code a broad range of analytical instrumentation, laboratory supplies, testing equipment, and consumables that support forensic analysis, water quality monitoring, environmental testing, materials characterization, and specialized scientific research at universities, public health agencies, environmental departments, and law enforcement crime laboratories. Recent opportunities show acquisitions spanning mass spectrometers, chromatography systems, specialized reagents for bacteriological testing, infiltration measurement equipment, motion-capture systems, rheometers, dynamic mechanical analyzers, and laboratory information management systems.

The issuing bodies skew heavily toward higher-education institutions, particularly state universities in Mississippi (Mississippi State University, University of Mississippi, University of Southern Mississippi), alongside state environmental and health departments (Oregon OSHA, Texas Health and Human Services Commission, Michigan EGLE), county government agencies (Brazoria County and Santa Clara County), and municipal labs (City of Philadelphia, City of Albuquerque). Mississippi State University appears repeatedly as a dominant buyer, with over a dozen sole-source procurements posted since late March 2026 for equipment ranging from rheological systems to wind-tunnel facilities. Geographic activity concentrates in the Southeast and Upper Midwest, with particular density in Mississippi, Oregon, Michigan, Texas, and Florida, though the code sees scattered activity across Wisconsin, Arizona, and other states. Representative recent opportunities include the State of Missouri Division of Purchasing's RFP for laboratory relocation services posted July 9, 2026 (due August 11) encompassing relocation of analytical instruments, hazardous chemicals, and forensic equipment across three state agencies; Texas Health and Human Services Commission's IFB for COLILERT reagents and water bottles posted July 1, 2026 (due July 8) for bacteriological water testing across eight counties; and Brazoria County, Texas's RFP for a Liquid Chromatograph-Triple Quadrupole Mass Spectrometer posted April 15, 2026 (due May 12) for the Sheriff's Office Crime Lab, budgeted at $300,000 with federal funding from the Paul Coverdell Forensic Sciences Improvement Grant. The overwhelming majority of recent postings are sole-source procurements at universities, reflecting both specialized equipment requirements and incumbent vendor relationships in research infrastructure.
