    Next, plates were washed with PBST and incubated with primary mouse anti-rat IgM HS antibody JM403 (Amsbio, Abingdon, United Kingdom, cat. no. # 370730-S, RRID: AB_10890960, 1 μg/ml in PBST) for 1 hour at RT.
    anti-rat IgM
    detected: (AMSBIO Cat# 370730-1, RRID:AB_10890960)
    Subsequently, plates were washed with PBST and incubated with secondary goat anti-mouse IgM HRP antibody (Southern Biotech, Uden, The Netherlands, cat. no. # 1020-05, RRID: AB_2794201, dilution 1:10000 in PBST) for 1 hour a RT.
    anti-mouse IgM
    detected: (SouthernBiotech Cat# 1020-05, RRID:AB_2794201)
    The plasma samples were 4 times diluted in PBST containing primary mouse anti-rat IgM HS antibody JM403 (1.3 μg/ml) and incubated for 1 hour at RT.
    anti-rat IgM
    suggested: None
    Plates were washed with PBST and incubated with secondary goat anti-mouse IgM HRP antibody for 1 hour at RT.

    SentencesResources
    Significance was determined by Fisher’s exact test to compare categorical variables, by Student’s t-test or Mann Whitney test to compare two groups and by Kruskal-Wallis test followed by Dunn’s test to compare more than two groups using GraphPad Prism V.8.4.2 (La Jolla, USA).

    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 Barzooka: We did not find any issues relating to the usage of bar graphs.


    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 is not a substitute for expert review. SciScore checks for the presence and correctness of RRIDs (research resource identifiers) in the manuscript, and detects sentences that appear to be missing RRIDs. SciScore also checks to make sure that rigor criteria are addressed by authors. It does this by detecting sentences that discuss criteria such as blinding or power analysis. SciScore does not guarantee that the rigor criteria that it detects are appropriate for the particular study. Instead it assists authors, editors, and reviewers by drawing attention to sections of the manuscript that contain or should contain various rigor criteria and key resources. For details on the results shown here, including references cited, please follow this link.

    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.
