    Antibodies
    SentencesResources
    Neutralization and antiviral assays: SARS-CoV-2 antibody concentrations were determined using the SARS-CoV-2 IgG II Quant assay and the Alinity I device (Abbott Diagnostics, Wiesbaden, Germany) with an analytical measurement range from 2.98– 5680 binding antibody units per mL (BAU/mL).
    SARS-CoV-2
    suggested: None
    Experimental Models: Cell Lines
    SentencesResources
    Titers were determined by the median tissue culture infective dose (TCID50) method as described by Spearman8 and Kaerber9 using Caco2 cells.

    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.
