Binding affinities determined by surface plasmon resonance spectrometry (BIACORE). Kinetics experiments were run in triplicate unless noted. In each kinetics experiment, compound was injected in triplicate at 7 different concentrations, ranging from 0 to 50 μ M. Mean KD values and standard deviations were calculated from three independent experiments for each compound.
NB= no binding.
Agg= aggregate formed during binding study.
