UNSPSC 41131616: Stabilized enzyme solution

In this classification, a stabilized enzyme solution is a reagent intended for medical purposes that is used to enhance the reactivity of red blood cells with certain antibodies, including antibodies that are not detectable by other techniques. These enzyme solutions include papain, bromelin, ficin, and trypsin. US FDA regulates Stabilized enzyme solution under 21 CFR 864.9400 and under FDA product code KSK.

UNSPSC 41131616 Stabilized enzyme solution is a Commodity code that encompasses biochemical additives and stabilized enzyme formulations used across state and local government operations. Recent state and local solicitations show minimal direct purchasing activity under this code's nominal scope; the recent opportunities tagged to this code do not reflect stabilized enzyme procurement. The California Emergency Medical Services Board solicitation (RFBIS27200126, due September 9, 2026) requests blood transfusion equipment and consumables for emergency medical transport, which falls outside enzyme-solution scope. The Hillsborough County Fire Rescue Department solicitation (ITB2600319, due July 24, 2026) seeks janitorial and operational supplies for 47 fire stations on an as-needed basis, similarly unrelated to stabilized enzyme products. State and local buyers under this code, when active, typically include state health departments, county medical examiners' offices, municipal laboratories, and transit authorities requiring enzyme-based diagnostic or maintenance applications.

Geographic activity under the code shows limited recent concentration. The two most recent opportunities span California and Florida, though neither reflects authentic enzyme-solution procurement. State and local procurement data for this Commodity code shows scant relevant recent activity, suggesting either low volume demand, narrow end-use specialization among purchasers, or systematic miscoding of related opportunities in state and local systems. Firms pursuing this code should monitor state laboratory services, clinical diagnostics, and specialized maintenance contracts where enzyme stabilization additives may appear under broader chemical or reagent categories rather than as a standalone Commodity line.
