Antibodies Sentences Resources Since the RBD-Fc construct was incompatible with our ELISA format due to the inclusion of Protein A to capture an α-myc antibody, ELISA was performed only for the RBD-vYFP (50 nM) and the ECD (25 nM) and later on with the S-2P (25 nM). α-mycsuggested: NoneExperimental Models: Cell Lines Sentences Resources 100–250 mL of suspension-adapted Expi293 cells (Thermo) were transiently transfected using Expifectamine according to the manufacturer protocol (Thermo), and expression was continued for 4–5 days in a humidified environment at 37°C, 8% CO2.

Expi293suggested: RRID:CVCL_D615)A second purified RBD construct, consisting of SARS-CoV-2 residues Arg319—Phe541 fused to a murine IgG1 Fc domain (RBD-Fc) expressed in HEK293 cells, was purchased from Sino Biological (Catalogue number: 40592-V05H, 300 μg were ordered) HEK293suggested: NoneSubsequently, S protein-pseudotyped VSV*ΔG(Luc) was added to Vero E6 cells grown in 96-well plates (25’000 cells/well). Vero E6suggested: NoneSoftware and Algorithms Sentences Resources Images were acquired in an automatic manner with SerialEM on a K2 summit detector (Gatan) in counting mode at ×49,407 magnification (1.012 Å pixel size) and a defocus range from −0.9 to −1.9 μm. SerialEMsuggested: (SerialEM, RRID:SCR_017293)A final non-uniform refinement in cryoSPARC further improved resolution down to 3.1 Å. cryoSPARCsuggested: (cryoSPARC, RRID:SCR_016501)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 did not find any issues relating to the usage of bar graphs.
Results from JetFighter: Please consider improving the rainbow (“jet”) colormap(s) used on pages 37, 38 and 39. At least one figure is not accessible to readers with colorblindness and/or is not true to the data, i.e. not perceptually uniform.
