The in vitro activities of the selected mAbs against HIV-1 infection in a pseudovirus/cell line neutralization assay. The antibodies in Fab format were tested against two clade B primary R5 isolates, Bal (a) and JRFL (b), and a clade B lab-adapted X4 isolate, IIIB (c). A CD4i human antibody domain (domain antibody, dAb), m36, was used as a positive control and an irrelevant human dAb targeting the human insulin-like growth factor 2 (IGF-2), 1A1, was used as a negative control.
