AccuSift provides high‑performance 4‑CPSEM (the marker residue of nitrofurazone) 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.4‑CPSEM (4‑[[[2‑(aminocarbonyl) hydrazinylidene]methyl]benzoic acid) is the main bound metabolite of the nitrofuran drug nitrofurazone in vivo. Its detection is a key method for monitoring drug residues in animal‑derived foods. Due to its high stability, 4‑CPSEM serves as a marker residue for monitoring nitrofuran drug use, which is banned in the EU and China.Performance Characteristics:
