Human Antibody Responses to HIV Type 1 Glycoprotein 41 Cloned in Phage Display Libraries Suggest Three Major Epitopes Are Recognized and Give Evidence for Conserved Antibody Motifs in Antigen Binding

Abstract excerpt

A large panel of human Fab fragments against the gp41 subunit of the HIV-1 envelope glycoprotein was isolated by panning six phage-displayed antibody libraries against recombinant gp41. The libraries were prepared from HIV-1-seropositive donors. Twenty-three Fabs recognizing conformation-dependent determinants on gp41 were isolated. Further selection of libraries against (1) gp41 ligated with Fabs from the...
