Figure 4From: Antiviral properties of two trimeric recombinant gp41 proteinsGp120 shedding. HeLa-Env or HeLaΔ20 were incubated for 6 h at 37°C with Rgp41A (0.03 μg/μl), Rgp41A buffer (same volume), sCD4 or PBS. Release of gp120 from the cell surface was quantified by ELISA. Values represent averages of duplicate samples from a typical experiment.Back to article page
