Antibodies Sentences Resources One day post-transfection, cells were infected with VSV(G*ΔG-luciferase)29 and after 2 h were washed five times with DMEM before adding medium supplemented with anti-VSV-G antibody (I1-mouse hybridoma supernatant, CRL-2700, ATCC) anti-VSV-Gsuggested: (LSBio (LifeSpan Cat# LS-C51761-50, RRID:AB_1277784)Experimental Models: Cell Lines Sentences Resources Briefly, HEK293T cells in DMEM supplemented with 10% FBS, 1% PenStrep seeded in 10-cm dishes were transfected with the plasmid encoding for the corresponding S glycoprotein using lipofectamine 2000 (Life Technologies) following manufacturer’s indications. HEK293Tsuggested: NonePseudovirus Neutralization: HEK293-hACE2 cells15 or VeroE6-TMPRSS214 were cultured in DMEM with 10% FBS (Hyclone) and 1% PenStrep and 8ug/mL puromycin for TMPRSS2 maintenance with 5% CO2 in a 37°C incubator (ThermoFisher). VeroE6-TMPRSS214suggested: NoneTo generate VSVΔG-based SARS-CoV-2 pseudovirus, BHK-21/WI-2 cells were transfected with the spike expression plasmid and infected by VSVΔG-firefly-luciferase as previously described30. BHK-21/WI-2suggested: RRID:CVCL_HB78)Lentivirus encoding hACE2-P2A-TMPRSS2 was made to generate A549-hACE2-TMPRSS2 cells which were maintained in DMEM supplemented with 10% fetal bovine serum and 1µg/mL puromycin. A549-hACE2-TMPRSS2suggested: RRID:CVCL_A5KB)Both viruses were propagated on Vero-TMPRSS2 cells and subjected to deep sequencing to confirm the presence of expected substitutions. Vero-TMPRSS2suggested: JCRB Cat# JCRB1818, RRID:CVCL_YQ48)Immune complexes were added to VeroE6-TMPRSS2 cell monolayers and incubated for 1 h at 37°C prior to the addition of 1% (w/v) methylcellulose in MEM. VeroE6-TMPRSS2suggested: JCRB Cat# JCRB1819, RRID:CVCL_YQ49)Experimental Models: Organisms/Strains Sentences Resources BALB/c mice for mRNA-1273 immunizations: Female BALB/c mice (6 to 8 weeks old) were obtained from Charles River Laboratories. BALB/csuggested: None1292S mice for mRNA-1273 immunizations: 129S2 mice (strain: 129S2/SvPasCrl, Cat # 287) were obtained from Charles River Laboratories and housed in a pathogen-free animal facility at Washington University in St. Louis. 129S2suggested: RRID:IMSR_CRL:287)129S2/SvPasCrlsuggested: RRID:IMSR_CRL:287)Recombinant DNA Sentences Resources Plasmid construction: The SARS-CoV-2-RBD-Avi construct was synthesized by GenScript into pcDNA3.1-with an N-terminal mu-phosphatase signal peptide and a C-terminal octa-histidine tag, flexible linker, and avi tag (GHHHHHHHHGGSSGLNDIFEAQKIEWHE). pcDNA3.1-withsuggested: NoneThe SARS-CoV-2 S ‘2P’ ectodomain trimer (GenBank: YP_009724390.1, BEI NR-52420) was synthesized by GenScript into pCMV with an N-terminal mu-phosphatase signal peptide and a C-terminal TEV cleavage site (GSGRENLYPQG) pCMVsuggested: RRID:Addgene_16459)The RBD-16GS-I53-50A fusion was cloned into pCMV/R using the Xba1 and AvrII restriction sites and Gibson assembly25. pCMV/Rsuggested: NonePseudovirus Neutralization Assay for BALB/c mRNA-1273 samples: Codon-optimized full-length spike genes (Wuhan-Hu-1 with G614, Beta, or Gamma) were cloned into pCAGGS vector. pCAGGSsuggested: RRID:Addgene_127347)Software and Algorithms Sentences Resources Animals were housed and maintained at the New Iberia Research Center (NIRC) of the University of Louisiana at Lafayette, an AAALAC International accredited institution, in accordance with the rules and regulations of the Guide for the Care and Use of Laboratory Animal Resources. NIRCsuggested: NoneRelative luciferase units were plotted and normalized in Prism (GraphPad). Prismsuggested: (PRISM, RRID:SCR_005375)Antibody-dose response curves were analyzed using non-linear regression analysis (with a variable slope) (GraphPad Software).
