    Antibodies
    SentencesResources
    A secondary biotinylated anti-mouse IgA, total IgG, IgG1, or IgG2a antibody (SouthernBiotech) was diluted 5,000-fold in 5-fold diluted PBSTBA and was added to plates for 2 h at RT.
    A secondary biotinylated anti-mouse IgA, total IgG, IgG1, or IgG2a antibody (SouthernBiotech)
    suggested: None
    anti-mouse IgA, total IgG
    suggested: None
    IgG1
    suggested: None
    IgG2a
    suggested: None
    Experimental Models: Organisms/Strains
    SentencesResources
    To isolate T cells, spleens from female Balb/cJ mice were dissociated in 2 mg/mL Collagenase D (Sigma-Aldrich, Cat# 11088882001) in Opti-MEM media (Gibco, Cat# 11058021) and filtered through a 40 μm cell strainer.
    Balb/cJ
    suggested: None
    Female BALB/c mice were intramuscularly injected with adjuvant-loaded NPs (4 mg/mouse) and variable doses of stabilized SARS-CoV-2 spike glycoprotein (BEI Resources, Cat# NR-52397) into the left and right anterior tibialis anterior muscles (50 μL NPs in saline per injection) on day 0 (prime) and day 28 (boost).
    BALB/c
    suggested: None
    Software and Algorithms
    SentencesResources
    MPLA loading estimation via GC-MS, LC-MS, and surrogate fluorometry has been previously described.28 PUUC and CpG loading was quantified by supernatant measurement of unbound RNA or DNA, respectively, with the Nucleic Acid Quantification workflow on a Synergy HT plate reader (BioTek) with Gen5 software.
    Gen5
    suggested: (Gen5, RRID:SCR_017317)
    FlowJo Software (BD) was used to generate t-distributed stochastic neighbor embedding (t-SNE) plots.
    FlowJo
    suggested: (FlowJo, RRID:SCR_008520)
    Statistical analyses were performed with GraphPad Prism 9.
    GraphPad Prism
    suggested: (GraphPad Prism, RRID:SCR_002798)
    For antibody quantification with ELISA, area under the curve (AUC) across fold dilutions was computed with the AUC function on GraphPad as previously reported.
    GraphPad
    suggested: (GraphPad Prism, RRID:SCR_002798)

    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).

    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.
