    Antibodies
    SentencesResources
    Antibody against nucleocapsid protein of anti-SARS-CoV-2 N protein (Genscript, USA) and GAPDH of anti-GAPDH (Proteintech, USA) were used at 1:3000 dilutions.
    Antibody against nucleocapsid protein of anti-SARS-CoV-2 N protein
    suggested: None
    anti-GAPDH
    suggested: None
    The second antibody of HRP-conjugated affinipure Goat anti-mouse IgG (H+L) were diluted at 1:20000.
    anti-mouse IgG
    suggested: None
    Experimental Models: Cell Lines
    SentencesResources
    Cell lines, coronavirus, and key reagents: Vero E6 cells (American Type Culture Collection, Manassas, VA, USA) and A549 cells were grown in high-glucose-containing Dulbecco's Modified Eagle Medium supplemented with 10% fetal bovine serum(13).
    A549
    suggested: None
    Blocking assay: To study whether the inhibition effects of skimmed breastmilk on SARS-CoV-2 pseudovirus and GX_P2V by binding cell surface to block viral entry, Vero E6 cells were seeded at the 96 well plate with 20,000 cells/well.
    Vero E6
    suggested: None
    Software and Algorithms
    SentencesResources
    Statistical analysis: Statistical analyses were analyzed using GraphPad Prism 8 software (GraphPad Software Inc.

    Results from OddPub: We did not detect open data. We also did not detect open code. Researchers are encouraged to share open data when possible (see Nature blog).


    Results from LimitationRecognizer: An explicit section about the limitations of the techniques employed in this study was not found. We encourage authors to address study limitations.

    Results from TrialIdentifier: No clinical trial numbers were referenced.


    Results from Barzooka: We found bar graphs of continuous data. We recommend replacing bar graphs with more informative graphics, as many different datasets can lead to the same bar graph. The actual data may suggest different conclusions from the summary statistics. For more information, please see Weissgerber et al (2015).


    Results from JetFighter: We did not find any issues relating to colormaps.


    Results from rtransparent:

    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.
