The Guava®SARS-CoV-2 Multi-Antigen Antibody Kit is a novel, bead-based immunoassay for flow cytometry that detects
IgG, IgM, and IgA antibodies against three SARS-CoV-2 antigens in parallel (nucleocapsid protein (N), Receptor-Binding
Domain (RBD) of the spike protein, and the S1 subunit of the spike protein (S1)) in serum and plasma samples. Easy visual
interpretation of results and fluorescence intensity information allow for the study of relative antibody levels, providing a more
comprehensive assessment of the immune response.
The Guava SARS-CoV-2 Antibody Kit has been optimized for use on the Guava® Muse® Cell Analyzer and Guava® easyCyte™ Systems, but samples can be run on any flow cytometer equipped with either a 488 nm or 532 nm laser.
