Fig. 1: Isolation and characterization of the antibody FD22 from patient P27.

a Neutralization titers (ID50, 50% inhibitory dilution and ID80, 80% inhibitory dilution) of the serum from patient P27 against 20 pseudoviruses representing clades A, CRF01_AE, B, CRF07_BC, and C. b Germline gene origins of the heavy- and light-chain variable regions of FD22 identified using the IMGT database (http://imgt.org). c Sequence alignment of the heavy- and light-chain variable regions of FD22.
