V3 loop mutations distinguish Env clones from the same subjects that display complete or incomplete inhibition of HIV-1 by MVC. The V3 loop amino acid sequences of Env clones displaying incomplete inhibition by MVC and one representative Env clone displaying complete inhibition are shown from 6 subjects. Dots indicate residues identical to the representative sensitive clone and dashes indicate gaps. The numbering is based on the HXB2 Env amino acid sequence. Sens: Representative Env clone displaying complete inhibition by MVC, Res: Envs clones that display incomplete inhibition by MVC
