Interaction of the αCP1-KH3 with the 30 nt of the 3′-UTR of AR mRNA measured by surface plasmon resonance. (A) 30 RU RNA was immobilized on a streptavidin-coated chip. Binding interactions were measured for a series of dilutions of the αCP1-KH3 domain from 10 to 0.625 μM for 2 min using flow rate of 50 μl/min. (B) Steady-state analysis of the interaction yielded a Kd value of 4.37 μM.
