    Antibodies
    SentencesResources
    Antibodies B38, H4, P2B-2F6, and S309 (42–44), were provided by Dr. Peter Kwong.
    H4
    suggested: None
    S309
    suggested: None
    Antibodies DH1041, DH1042, DH1043, and DH1047 were provided by Drs.
    DH1042
    suggested: None
    DH1043
    suggested: None
    Structural analyses: We used PDB: 7C2L (50) for the full trimeric spike structure, and antibody spike complex structures from Li et al. (45) for DH1041-DH1047 antibodies, PDB: 6WPS (44) for S309, PDB: 7BWJ (43) for P2B-2F6, and PDB: 6XDG for REGN antibodies (51).
    DH1041-DH1047
    suggested: None
    P2B-2F6
    suggested: None
    For B38, to identify the most amenable Y-501 rotamers, the N501Y mutation was modeled with the antibody-RBD complex; however, all identified rotamers induced substantial clashes and the rotamer with the least clash was retained.
    antibody-RBD
    suggested: None
    Experimental Models: Cell Lines
    SentencesResources
    Transfection mixtures were added to pre-seeded HEK 293T/17 cells in T-75 flasks containing 12 ml of growth medium and incubated for 16-20 hours at 37°C.
    HEK 293T/17
    suggested: ATCC Cat# CRL-11268, RRID:CVCL_1926)
    Software and Algorithms
    SentencesResources
    Antibody epitope, electrostatics and polar bonds calculations as well as mutation modeling were performed in PyMOL (The PyMOL Molecular Graphics System, Version 2.0 Schrödinger, LLC.).
    PyMOL
    suggested: (PyMOL, RRID:SCR_000305)
    To correct for multiple test corrections, false discovery rates (FDR or q values) were calculated as in (52) implemented in a Python package (https://github.com/nfusi/qvalue) for Python version 3.4.2.
    Python
    suggested: (IPython, RRID:SCR_001658)

    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.
