Fig. 2From: In vitro antiretroviral activity and in vivo toxicity of the potential topical microbicide copper phthalocyanine sulfateEffect of CuPcS on Pseudovirus Infection of TZM-BL Cells. Copper phtahlocyanine sulfate (CuPcS) was combined with nine different Subtype B, HIV-1 pseudoviruses for one hour prior to addition of TZM-BL cells. Level of infectivity was determined by using a p24 assay performed in triplicate and was observed to have dose–response effectBack to article page
