Cell protection against HIV-1 infection. β-gal activity was measured after HeLa/CD4-LTR-β-gal cells were exposed to bDLE (2 IU) for 30 minutes, washed and exposed to HIV-1IIIB cell-free virus at various time points post-treatment. Percentage values are relative to the positive control (infected cells without drug pretreatment). The data represent the means ± standard deviations from three separate experiments, each of which was carried out in duplicate.
