The V-PLEX SARS-CoV-2 Panel 27 (IgA) Kit is a multiplex serology assay for antibodies to Spike antigens from variants of SARS-CoV-2. It includes antigens from Beta, Delta, and several sublineages of Omicron, including BA.2, BA.2.12.1, BA.3, BA.4, BA.5, and two BA.2 Spike antigens with extra mutations predicted to further evade neutralization. Panel 27 includes: A (WT), (B.1.351), (B.1.617.2; AY.4) Alt Seq 2, (BA.2; BA.2.1; BA.2.2; BA.2.3; BA.2.5; BA.2.6; BA.2.7; BA.2.8; BA.2.10; BA.2.10.1; BA.2.12), (BA.2.12.1), (BA.2+L452M), (BA.2+L452R), (BA.3), (BA.4), and (BA.5).

Note: Alternative S-GENE mutations for Spike of B.1.617.2 are listed as "Alt Seq #."
