    Antibodies
    SentencesResources
    Production of human anti-SARC-CoV-2 spike monoclonal antibodies: Previously reported naturally occurring human monoclonal antibodies of B38 (Wu et al., 2020), REGN10987 (Hansen et al., 2020), and CR3022-B6 (Rouet et al., 2020), specific to the receptor binding domain (RBD) of the spike protein one (S1) of the SARS-CoV-2 virus were re-produced as previously reported (HuaAn McAb Biotechnology).
    anti-SARC-CoV-2
    suggested: None
    CR3022-B6
    suggested: None
    Antibody injection: The purified and endotoxin-free IgG of the anti-coronavirus antibodies used for the animal model include rabbit polyclonal anti-COVID-19 S1, anti-SARS-CoV S, and the human monoclonal anti-COVID-19 S1, B38 (Wu et al., 2020), REGN10987 (Hansen et al., 2020), and CR3022-B6 (Rouet et al., 2020).
    anti-coronavirus
    suggested: None
    anti-SARS-CoV S,
    suggested: (BioLegend Cat# 944301, RRID:AB_2890871)
    In addition, two dosages of BH-103 injection (IP) at either day before or the same day of each antibody injection of the 4 pathogenic antibodies (anti-COVID-19 S1, anti-SARS-CoV S, REGN10987, and B38) were administrated, respectively.
    anti-COVID-19
    suggested: None

    SentencesResources
    Digestion of A549 and NB4 cells with neuraminidase: The cells of human lung epithelium cell line A549 (ATCC), and human acute promyelocytic leukemia cell line NB4 (ATCC) were washed once with the digestion buffer for neuraminidase (Roche), the cells were centrifuged at 2000 rpm for 5 minutes, and the supernatant was discarded.
    A549
    suggested: None
    A549 or NB4 cells without the treatment of neuraminidase were used as controls.

    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.
