ATA effect on the binding of [125I]-IFN-α2b to sensitive (DWS) Daudi cells. At the concentrations indicated, ATA was added at 90 minutes after saturation of the IFNAR with [125I]-IFN-α2b (5,000 IU/mL at 4°C for 90 minutes) or at 18 hours before this saturation. Specific binding curves show both competitive binding of the ATA and displacement of bound [125]I-IFN-α2b (mean of duplicated experiments).
