    Antibodies
    SentencesResources
    The samples were then subjected to SDS–PAGE and analysed by western blotting using an anti-Histidine antibody (Thermo Scientific) to detect Spike and ACE2, an anti-rabbit antibody (Santa Cruz Biotechnology) to detect Ab-CR3022 and an anti-ACE2 antibody (EMP Millipore Corp) to detect ACE2-Fc by chemiluminescent revelation39.
    anti-Histidine
    suggested: None
    anti-rabbit
    suggested: None
    anti-ACE2
    suggested: None
    The same protocol, using empty beads (without Spike), was performed as a negative control for each system. gFET functionalization: ACE-Fc, ACE2 and anti-Spike antibody were covalently immobilized over the fabricated gFET chip (Graphenea gFET-S20) through PBASE.
    anti-Spike
    suggested: (Imported from the IEDB Cat# s20, RRID:AB_2847993)
    Experimental Models: Cell Lines
    SentencesResources
    Purification of Trimeric Spike protein from FreeStyle HEK293-F cells: The plasmid for expression of the SARS-CoV-2 prefusion-stabilized Spike ectodomain in HEK293-F cells (Thermo Fisher) was a generous gift from the McLellan laboratory at the University of Texas at Austin36.
    HEK293-F
    suggested: RRID:CVCL_6642)
    Software and Algorithms
    SentencesResources
    After glycine treatment, samples were rinsed with PBS (pH 7.4, 1X), DI water and dried with N2. gFET characterization using Raman and AFM: AFM measurements were performed with a SOLVER PRO from NT-MDT, RMS was evaluated by using Nova Px software.
    SOLVER
    suggested: (Solver, RRID:SCR_008510)

    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:
    • Thank you for including a conflict of interest statement. Authors are encouraged to include this statement when submitting to a journal.
    • Thank you for including a funding statement. Authors are encouraged to include this statement when submitting to a journal.
    • No protocol registration statement was detected.

    Results from scite Reference Check: We found no unreliable references.


    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.
