Antibodies Sentences Resources Anti-mouse whole IgG horseradish peroxidase conjugates (Jackson Laboratory) were used as secondary antibodies, and 3,5,3′5′-tetramethylbenzidine (TMB) (KPL, Gaithersburg, MD) was used as the substrate. Anti-mouse whole IgG horseradish peroxidase conjugatessuggested: NoneAnti-mouse whole IgGsuggested: NoneAfter wash three times with PBS-T buffer, the membrane was incubated half hour with anti-mouse IgG horseradish peroxidase conjugates (Jackson Laboratory) as secondary antibody. anti-mouse IgGsuggested: NoneThe frequency of cc40.8 class antibody was calculated by masking IGHV3-23 with 94ITMA, 101V and 102V on 8 amino acids CDR H3 and IGLV3-10 with T91, 94SGN, and A96 on 11 amino acids CDR L3. 94SGNsuggested: NoneExperimental Models: Cell Lines Sentences Resources Cell Lines: FreeStyle 293-F (cat# R79007) and Expi293F cells (cat# A14528; RRID: CVCL_D615) were purchased from ThermoFisher Scientific Inc Expi293Fdetected: ( RRID:CVCL_D615)FreeStyle 293-F cells were maintained in FreeStyle 293 Expression Medium, while Expi293F cells were maintained in Expi Expression Medium. Expi293Fsuggested: RRID:CVCL_D615)Analysis of WS6 binding to cell surface expressed spike protein: Expi-293 cells were transiently transfected with plasmids encoding full-length spike proteins of coronaviruses using Turbo293 transfection reagent (Speed BioSystems) following manufacturer’ s protocol. Expi-293suggested: Nonetransducing plasmid pHR’ CMV-Luc, a TMPRSS2 plasmid and S plasmids from human and animal coronaviruses (SARS-CoV-2 variants, SARS-CoV, MERS-CoV and SARS-CoV-2, SARS-CoV related coronaviruses) into 293T cells using Lipofectamine 3000 transfection reagent (L3000-001, ThermoFisher Scientific, Asheville, NC) (Naldini et al., 1996). 293Tsuggested: None293T-ACE2 cells (provided by Dr. Michael Farzan) or 293 flpin-TMPRSS2-ACE2 cells (made at the VRC) were plated into 96-well white/black Isoplates (PerkinElmer, Waltham, MA) at 75,00 cells per well the day before infection of pseudovirus. 293T-ACE2suggested: NoneExperimental Models: Organisms/Strains Sentences Resources BALB/cJ mice (Jackson Laboratory), 6- to 8-week-old female, were used. BALB/cJsuggested: NoneRecombinant DNA Sentences Resources DNA sequences encoding diverse beta-coronavirus S2P proteins were cloned into mammalian expression vector pVRC8400 and the proteins expressed by transient transfection of FreeStyle 293-F cells as previously described (Zhou et al., 2020b). pVRC8400suggested: RRID:Addgene_63163)Spike-containing lentiviral pseudovirions were produced by co-transfection of packaging plasmid pCMVdR8.2, pCMVdR8.2suggested: RRID:Addgene_8455)transducing plasmid pHR’ CMV-Luc, a TMPRSS2 plasmid and S plasmids from human and animal coronaviruses (SARS-CoV-2 variants, SARS-CoV, MERS-CoV and SARS-CoV-2, SARS-CoV related coronaviruses) into 293T cells using Lipofectamine 3000 transfection reagent (L3000-001, ThermoFisher Scientific, Asheville, NC) (Naldini et al., 1996). pHR’suggested: NoneTMPRSS2suggested: RRID:Addgene_53887)Software and Algorithms Sentences Resources Production of antibodies: Antibody heavy and light variable region gene sequences were synthesized (Gene Universal Inc, Newark DE) and subcloned into corresponding pVRC8400 vectors (https://www.addgene.org). https://www.addgene.orgsuggested: (Addgene, RRID:SCR_002037)Flow cytometry data were acquired in a BD LSRFortessa X-50 flow cytometer (BD biosciences) and analyzed using Flowjo (BD biosciences) Flowjosuggested: (FlowJo, RRID:SCR_008520)Percent neutralization and neutralization IC50s, IC80s were calculated using GraphPad Prism 8.0.2. GraphPad Prismsuggested: (GraphPad Prism, RRID:SCR_002798)The structures were determined by molecular replacement with Phaser (McCoy et al., 2007) in the CCP4 Program Suite (Collaborative Computational Project, 1994) CCP4suggested: (CCP4, RRID:SCR_007255)Further refinement was carried out with PHENIX (Adams et al., 2010), starting with torsion-angle simulated annealing with slow cooling. PHENIXsuggested: (Phenix, RRID:SCR_014224)Iterative manual model building was carried out with COOT (Emsley and Cowtan, 2004) with maps generated from combinations of standard positional, individual B-factor and TLS refinement algorithms. COOTsuggested: (Coot, RRID:SCR_014222)Antibody germline assignment: Germline gene of heavy and light chain were assigned by querying nucleotide sequences on IGBLAST server. Germlinesuggested: (GERMLINE, RRID:SCR_001720)IGBLASTsuggested: (IgBLAST, RRID:SCR_002873)Beta-coronavirus spike sequences were downloaded from NCBI server using accession codes listed in Full-length spike constructs.
