Figure 3. SPR measurements of the interaction between Vpr and full-length or C-terminal Impα isoforms using BIAcore.

Figure 3

(A) SPR sensorgrams of the interactions between GST-Vpr and the full-length Impα isoform, NPI-1full, immobilized to the CM sensor chip. Sensor curves of the interactions between Vpr at various concentrations (0 to 40 µM) and NPI-1full are shown. (B) The analysis curves used to obtain the dissociation constants (KD) for the interactions between Vpr and the Impα isoforms, Rch1full, Qip1full, NPI-1full, Rch1404-529, Qip1392-537 and NPI1404-541 using the steady state binding model equation (see Material and Methods).
