FIG. 6.
Anti-HIV activity of −2 RANTES released from vehicle formulations. Samples collected after 120 min of dialysis were tested in infectivity assays with HIV-1BaL (see Materials and Methods). After 6 days, infection was determined as a function of HIV p24 levels in the culture supernatants. Replicate values were averaged and were used to generate dose-effect curves. The curves were used to calculate the IC50 of each test formulation. An average value from two independent experiments is presented.
