REAGENTS AND METHODS FOR IDENTIFYING ANTI-HIV COMPOUNDS

摘要

Single-molecule imaging techniques have been applied herein and have demonstrated the conformation states of HIV-1 Env. The introduction of small organic fluorophores at selected positions within HIV-1 Env that do not affect infectivity permits the detection of changes in inter-dye distances as a measure of conformational changes. Implementation of the smFRET-based technologies disclosed herein enable conformational screening for molecules that block, induce or trap HIV-1 Env in specific conformational states. Methods for identifying anti-HIV drugs in a smFRET-based screening, and various reagents useful for implementation of such methods, are provided.
