The Luciferase Immunoprecipitation System (LIPS) Targeting the Spike Protein of SARS-CoV-2 Is More Accurate than Nucleoprotein-Based LIPS and ELISAs for Mink Serology

Distribution of RLU values generated using the sera from naturally SARS-CoV-2-infected mink samples across (a) the threshold line for the LIPS-S assay with the indication of PRNT results and sera sampling dates, (b) LIPS-N assay with threshold line, identification of PRNT results, and sera sampling dates, (c) LIPS-N assay with threshold line, identification of Eradikit results, and sera sampling dates, and (d) LIPS-N assay with threshold line, identification of IDV results, and sera sampling dates. Negative samples are located below the blue threshold line of mean plus five standard deviations.
