AccuSift provides high‑performance fluorescent brightener KSN competitive assay pairings, characterized by exceptional batch‑to‑batch consistency and optimized for IVD kit development (Lateral Flow, Chemiluminescence, ELISA, POCT). These pairings offer high affinity and specificity, facilitating rapid detection.Fluorescent Brightener KSN is a distyryl bis‑benzimidazole compound that exhibits superior whitening performance compared to OB‑1 in synthetic materials such as polyester fibers, plastics (e.g., PET, PC, ABS, PVC), and polyamides. It offers good compatibility and low usage levels.Fluorescent brighteners are organic compounds that absorb ultraviolet light and emit blue‑violet fluorescence, widely used in paper, textiles, detergents, and plastics. However, their potential biotoxicity and environmental persistence have raised significant concerns.Performance Characteristics:
