In Vitro Evaluation of Experimental Agents for Anti‐<scp>HIV</scp> Activity

Abstract

This unit presents an assay that has proven useful as an initial screening test is an HIV cytopathic effect (CPE) inhibition assay in which immortalized T cell lines (e.g., ATH8 or MT2) that are profoundly sensitive to the cytopathic effect of certain strains of HIV are utilized as target cells. Additional protocols assess the anti-HIV activity of certain candidate agents by measuring inhibition of syncytium formation or p24 gag protein production by ELISA. Calculation of the 50% inhibitory concentration (IC(50)) is also presented.
