In this study, a sensitive and specific monoclonal antibody against VIR M1 was produced based on a new hapten. The antibody had a linear detection range of 3.77-65.51 ng/mL with an IC(50)of 15.26 ng/mL and good specificity for VIR M1. Gold nanoparticle (GNP)-based lateral flow strips were assembled for rapid screening of VIR M1 in feed samples. When evaluated with the naked eye, the visual limit of detection (LOD) in feed samples was 25 mu g/kg, and the cut-off value was 200 mu g/kg. Therefore, this GNP-based lateral flow strip assay can be used for on-site detection and rapid preliminary screening of VIR M1 in feed samples.
