    Antibodies
    SentencesResources
    Primary antibodies used were goat anti-mouse ACE2 (AF3437, R and D Systems), goat anti-mouse ACE (AF1513, R&D Systems), and rabbit anti-mouse actin (4967, Cell Signaling).
    anti-mouse ACE2
    suggested: None

    anti-mouse actin ( 4967 , Cell Signaling) .
    suggested: None
    After extensive washing (three times for 15 min each in TBS containing 0.1% Tween 20), proteins were detected with horseradish peroxidase-coupled anti-goat or anti-rabbit antibody.
    anti-goat
    suggested: None
    anti-rabbit
    suggested: None

    Software and Algorithms
    SentencesResources
    Densitometry analysis was performed using ImageJ software (NIH, USA), and a β-actin control was used to confirm equal sample loading and normalization of the data.

    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: We found the following clinical trial numbers in your paper:

    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.

    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.
