Here, we describe a serological enzyme-linked immunosorbent assay for the screening and identification of human SARS-CoV-2 seroconverters. This assay does not require the handling of infectious virus, can be adjusted to detect different antibody types in serum and plasma and is amenable to scaling. Serological assays are of critical importance to help define previous exposure to SARS-CoV-2 in populations, identify highly reactive human donors for convalescent plasma therapy and investigate correlates of protection.

We thank Y.-Z. Zhang (Fudan University) and E. Holmes (University of Sydney) for sharing the sequence of the first SARS-CoV-2 isolate in a very timely manner. We thank J. Garlick and J. Roney (Alfred Hospital, Melbourne) for data and specimen collection, N. Aboelregal for making many different NHIG products (Mount Sinai) available and L. Martinez-Sobrido (Texas Biomedical Research Institute) for initially characterizing mAb 1C7. We are also thankful to Genewiz for speeding up gene synthesis for this project, and for being very accommodating to our needs. Furthermore, we thank D. Tidmore for help with ordering primers quickly, and finally S. Dong for commuting to New Jersey on several occasions to pick up reagents from Genewiz. We also thank the Mount Sinai Health System Translational Science Hub 'ConduITS' (NIH grant U54TR001433) for supporting sample collection.
