File S1 - Aqueous Extracts of the Marine Brown Alga Lobophora variegata Inhibit HIV-1 Infection at the Level of Virus Entry into Cells

Figure S1 and supplemental experimental procedures. Figure S1: Time-dependent effect of the L. variegata aqueous extract on the viability of Hela cells. A time series of the effect of the L. variegata aqueous extract on viability of Hela cells was determined by a colorimetric XTT assay. Hela cells were treated with a fixed concentration of 400 µg/ml of the extract for time periods of one day up to 7 days. Data are given relative to untreated cells measured at the same time point (100%). (DOCX)
