    Oligos were synthesized as a single pool by Twist Biosciences, followed by PCR amplification, restriction enzyme digestion and cloning into a commercially available T7 vector as previously described13,14. VirScan Bioinformatics: Sequencing reads were aligned to a reference database comprising the full viral peptide library using the Bowtie2 aligner35.

    Results from LimitationRecognizer: We detected the following sentences addressing limitations in the study:
    Our study has some limitations. To fully characterize the test performance characteristics of these 9 candidate antigens as the basis for a more specific, high-throughput clinical diagnostic assay, additional patient samples need to be analyzed. However, both the statistically significant enrichment of these antigens above pre-pandemic healthy controls by PhIP-Seq, and the rigorous comparison between staining on HCs and COVID-19 subjects to determine a positive signal on the ReScan microarrays are both supportive of these antigens being highly specific for SARS-CoV-2 exposure. The current IP strategy focuses only on IgG, but future work may center on IgM targets, given their role in the early humoral immune response. Finally, post-translational modifications and tertiary or quaternary conformational epitopes are not represented in the T7 phage display system used here15,34. The immediate focus of this study was to develop a blueprint for candidate antigens to include in confirmatory SARS-CoV-2 serologic assays and identify a panel of linear antigens with significant discriminatory power. Beyond their use for diagnostic purposes, the next and critical question is whether a patient’s antibody repertoire confers protective immunity. Because our assay characterizes patients’ antibodies to multiple SARS-CoV-2 antigens, it enables deeper phenotyping of the adaptive immune response that, in future studies, can be correlated with acute and long-term clinical outcomes.

    About SciScore

    SciScore is an automated tool that is designed to assist expert reviewers by finding and presenting formulaic information scattered throughout a paper in a standard, easy to digest format. SciScore checks for the presence and correctness of RRIDs (research resource identifiers), and for rigor criteria such as sex and investigator blinding. For details on the theoretical underpinning of rigor criteria and the tools shown here, including references cited, please follow this link.
