Inhibition of HIV-1 and HIV-2 Env-mediated fusion. AMD3100 or Leu3A were added to cocultures of HIV-expressing cells and target cells at the time of co-culture and fusion was measured as described in Methods. IC50 values were derived from dose-response by fitting the data to a hyperbolic decay function.
