December 2021—Bio-Rad Laboratories launched its Bio-Plex Pro Human IgA and IgM SARS-CoV-2 panels to detect IgA and IgM antibodies against four SARS-CoV-2 antigens.
The two new panels along with the company’s existing Bio-Plex Pro Human IgG SARS-CoV-2 N/RBD/S1/S2 4-Plex panel aim to assist researchers in developing vaccines and to help public health researchers who perform seroprevalence studies based on serology specimens identify individuals who may have been exposed to SARS-CoV-2.
The three panels are separate, ready-to-use 96-well kits containing premixed magnetic capture beads, an isotype-specific detection antibody, positive and negative controls, and buffers. Individual assay components are also available, offering the option to assay only the antibodies of interest. Viral-protein–coated beads can be used to assay antibodies in multiple species and need only to be paired with a species-specific biotinylated antibody for detection.
