Why Developers Choose Meridian Blockers • Proven performance across ELISA, CLIA, and lateral flow platforms • Active and passive blocking strategies available • Animal-free recombinant options to support supply security and regulatory alignment • Formulations designed to preserve assay signal while reducing non-specific binding • Suitable for incorporation into sample diluents or assay buffers • Scalable manufacturing for commercial diagnostic production
Minimize Interference. Maximize Diagnostic Confidence. Heterophilic antibodies , human anti-mouse antibodies ( HAMA ), and rheumatoid factor ( RF ) can compromise assay accuracy, particularly in high-sensitivity platforms. Meridian’s immuno- assay interference blockers are designed to improve specificity and reduce false results across clinical testing environments.
