Characterization of clones of HIV-1 infected HuT 78 cells defective in gag gene processing and of SIV clones producing large amounts of envelope glycoprotein.

Abstract excerpt

Single-cell clones of HIV-1 (FRE-3) or SIV/Mne infected HuT 78 cells were obtained by plating dilutions of virally infected HuT 78 cells on a monolayer of sheep choroid plexus cells in 96-well microtiter plates. Several of these clones produce HIV-1 virus mutants that accumulate the gag precursor polyprotein and lack a functional protease. These protease-deficient viruses are non-infectious and consist of...
