Fig. 5: Isolation of trimer-specific monoclonal antibodies from an animal (272.8) with potent neutralization activity against BG505.T332N post vaccinations with DNA-encoded BG505.MD39.

a Vaccination and tissue collection scheme for 272.8. b Trimer-specific binding antibody responses in 272.8 2 weeks post the final vaccination. c Autologous BG505.T332N neutralizing activity induced in 272.8 2 weeks post the final vaccination. d Gating strategy used to isolate antigen-specific CD19 + IgD− IgM− BG505.MD39-Tetramer-FITC + BG505.MD39-Tetramer-PE + B-cells from spleen and lymph nodes of 272.8 2 weeks post the final vaccination. e Characteristics of isolated murine monoclonal antibodies in terms of germline VH and VL gene usage.
