简介：
Overview
This article presents a high-throughput method for monitoring antibody titers of IgA, IgM, or IgG in response to SARS-CoV-2 infection or vaccination. The 'Multianalyte Covid-19 Immune Response Panel' utilizes coded microspheres and a flow-based multiplex reader for concurrent analysis.
Key Study Components
