Fig. 2From: Characterization of resistance to a potent d-peptide HIV entry inhibitorProtein interaction analysis of Q577R mutation. SPR equilibrium binding data (in triplicate) for interaction between immobilized IZN36 (WT or Q577R) and PIE12 monomer. The calculated KD values are 0.031 µM for WT and 2.0 µM for Q577RBack to article page
