    Antibodies
    SentencesResources
    The anti-His tag antibodies, diluted at 50 μg/mL in 10 mM sodium acetate, pH 4.5, were immobilized on both the active and reference flow cells surface of the activated CM5 sensor chip using amine coupling method.
    anti-His tag
    suggested: None
    Approximately 200 RU of His-tagged SARS-CoV-2 and SARS-CoV spike trimers and RBDs were captured onto the chip for the active surface, and anti-His antibody alone served as the reference surface.
    anti-His
    suggested: None
    Experimental Models: Cell Lines
    SentencesResources
    Cell lines: HEK293T/17 (cat# CRL-11268) and Vero E6 cells (cat# CRL-1586) were from ATCC, 293T-ACE2 cells were kindly provided by J. Sodroski of Harvard Medical School, and they were cultured in 10% fetal bovine serum (FBS, GIBCO cat# 16140071) supplemented Dulbecco’s Modified Eagle Medium (DMEM, ATCC cat# 30-2002) at 37°C, 5% CO2.
    Vero E6
    suggested: None
    293T-ACE2
    suggested: None
    Briefly, HEK293T cells were grown to 80% confluency before transfection with the spike gene using Lipofectamine 3000 (Invitrogen).
    HEK293T
    suggested: None
    The proteins were expressed in HEK293 Freestyle cells (Invitrogen) in suspension culture using serum-free media (Invitrogen) and transfected into HEK293 cells using polyethyleneimine (Polysciences).
    HEK293
    suggested: None
    Software and Algorithms
    SentencesResources
    The results were then converted into percentage neutralization at a given sample dilution or mAb concentration, and the averages ± SEM were plotted using a five-parameter dose-response curve in GraphPad Prism v.8.4.
    GraphPad Prism
    suggested: (GraphPad Prism, RRID:SCR_002798)
    Data processing was performed using cryoSPARC v2.15 [14].
    cryoSPARC
    suggested: (cryoSPARC, RRID:SCR_016501)
    Model building and refinement: The 2-36-RBD complex model was built starting from template PDB structures 6BE2 (Fab) and 7BZ5 (RBD) using Phenix Sculptor.
    Phenix Sculptor
    suggested: None
    Automated and manual model building were iteratively performed using real space refinement in Phenix [16] and Coot [17].
    Phenix
    suggested: (Phenix, RRID:SCR_014224)
    Coot
    suggested: (Coot, RRID:SCR_014222)
    Geometry validation and structure quality assessment were performed using Molprobity [18].
    Molprobity
    suggested: (MolProbity, RRID:SCR_014226)
    The visualization of sequence entropy was displayed by PyMol version 2.3.2.
    PyMol
    suggested: (PyMOL, RRID:SCR_000305)

    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.
