UNSPSC 41106102: Differential display or subtraction kits

UNSPSC 41106102 Differential display or subtraction kits (Commodity) encompasses DNA extraction reagents, consumables, and STR amplification kits used in forensic casework, newborn screening, and DNA analysis programs. State and local governments procure these materials primarily through forensic crime laboratories, public health agencies, and specialized diagnostic facilities that run DNA profiling, extraction, and PCR testing operations. Recent solicitations show purchases of named-brand kits such as RapidHIT consumables for human identification, QuantaBio extraction reagents for newborn screening (Severe Combined Immunodeficiency and Spinal Muscular Atrophy detection), Promega PowerPlex STR amplification kits, and Life Technologies reagent lines. The issuing bodies are predominantly state forensic laboratories and state health agencies—the Texas Department of Public Safety Crime Lab, Texas Health and Human Services Commission, Mississippi Forensic Laboratory, and Illinois State Police—though municipal water and wastewater utilities occasionally procure related analytical testing services.

Recent activity concentrates in Texas and Mississippi, with secondary activity in Illinois and Florida. The Texas DPS Crime Lab posted an IFB for DNA consumables (RapidHIT product line, 40 units swabs, 20 units sample kits, cartridges, controls) on July 7, 2026, with responses due July 22, 2026 and award anticipated July 27. The Texas HHSC issued an IFB for DNA extraction reagents supporting newborn screening (QuantaBio Extracta DBS and PerfeCTa qPCR ToughMix UNG, estimated annual spend $2.5 million, initial contract term September 1, 2026 through August 31, 2027 with four optional one-year renewals) with responses due July 15, 2026. The Illinois State Police solicited an indefinite-quantity, nine-year IFB for PowerPlex STR amplification kits (Promega brand, delivery within 60 days of purchase order) with a February 20, 2026 response deadline. The Mississippi Forensic Laboratory posted an RFI for Life Technologies kits and consumables due July 21, 2026. Most procurements are sole-source or proprietary, explicitly naming manufacturer brands and restricting competition to authorized dealers; best-value evaluation criteria predominate, with price a significant but not sole factor.
