BT-plex™ Human Anti-SARS CoV2 Spike Protein Antibody kit is a bead-based immunoassay, using a magnetic fluorescence-encoded bead optimized for use on regular flow cytometers. The assay simultaneously quantifies specific human anti-SARS CoV-2 spike protein IgG, IgM, and IgA in the same sample. The assay has been analytically validated for use on serum/plasma samples. The assay kit provides better detection sensitivities, broader dynamic ranges, and less hands-on time than traditional ELISA methods. 


Kit Components:  Magnetic beads immobilied with S Trimer protein, Standard cocktail containing human anti-SARS CoV2 RBD monoclonal antiboies with IgG, IgM, and IgA isotype, Detection antibodies for human IgG, IgM, and IgA isotypes, SAPE reporter, Assay buffer, Wash Buffer, V-bottom 95-well plate, and plate sealers


Size: 100 tests


Sample type: serum/plasma (1:500) and other sample types


Protocol time: 3.5 hours


Limit of detection: 5 pg/mL for IgG, IgM; 2.5 pg/mL for IgA


Dynamic range:  6 pg/mL to 25 ng/mL


Accuracy: 80-100%


Precisions:  Intra-assay CV < 10%;  Inter-assay CV < 15%
