UNSPSC 41181608: Radial immunodiffusion plate

In this classification, Radial immunodiffusion plate connotes a device used to that consists of a plastic plate to which agar gel containing antiserum is added. In radial immunodiffusion, antigens migrate through gel which originally contains specific antibodies. As the reagents come in contact with each other, they combine to form a precipitate that is trapped in the gel matrix and immobilized. US FDA regulates Radial immunodiffusion plate under 21 CFR 866.4800 and under FDA product code JZQ.

UNSPSC 41181608 Radial immunodiffusion plate is a Commodity code, but the recent state and local opportunities posted under this code show no activity aligned with the immunodiagnostic testing or laboratory supplies explicitly named in the code. The opportunities identified include sealed bids for timeclock equipment (Mississippi State University), hydrogen generator supplies (City of Philadelphia), fire alarm system components (Mississippi State University), spectrometer instrumentation (Mississippi State University), bacteriological water testing reagents (Texas Health and Human Services Commission), X-ray diffractometer components (State of Oregon), and various other laboratory and specialized equipment procurements that bear no connection to radial immunodiffusion testing plates or immunological assay supplies. The code appears dormant or mistagged in current state and local procurement systems; no issuing body has posted a solicitation seeking the diagnostic plates or related immunodiffusion test kits that the commodity code nominally describes.

The geographic spread of recent postings spans Texas, Mississippi, Oregon, Pennsylvania, Florida, and Wisconsin, with Mississippi State University appearing frequently as a sole-source purchaser across unrelated commodities. This frequency reflects the university's use of a shared procurement code structure rather than concentration in the immunodiagnostics space. No representative recent opportunities exist that would signal either market activity or procurement intent under this commodity code. If your firm supplies radial immunodiffusion plates or related clinical laboratory immunoassay products to state and local health departments, public health laboratories, or hospital systems, monitor state health agency RFQs, disease-surveillance lab acquisitions, and multi-year clinical chemistry supply contracts directly rather than tracking this code.
