Supporting IVD manufacturers with critical diagnostic reagents

Critical assay components that support diagnostic performance, reproducibility and scalable manufacturing

Reagent components form the foundation of immunodiagnostic and molecular diagnostic assays, influencing analytical sensitivity, specificity, reproducibility and overall assay performance. From antibody-antigen interactions to nucleic acid amplification chemistry, reagent quality directly impacts the reliability of diagnostic results.

LGC supplies critical assay components used throughout the development lifecycle, including antibodies, antigens, recombinant proteins, molecular biology enzymes, PCR and RT-qPCR reagents, competent cells and specialised biological materials. These reagents support applications ranging from infectious disease and serology testing to molecular diagnostics and translational research.

Drawing on expertise across the LGC Diagnostics & Genomics portfolio, we help assay developers and manufacturers access high-quality materials, technical support and scalable supply solutions that support assay validation, regulatory readiness and commercial manufacturing.
