Figure 4

(a) EPR spectra of spin labeled eptifibatide 3 (blue), (b) bis-sulfone based spin label 4 (orange) and (c) TEMPO as reference (black). Note: Spectra are normalized by the maximum intensity (left side). Spectra are shown without normalization (right side). Experimental conditions were identical for all samples. Samples were measured at concentrations of 1 mM in DMSO at 293 K.
