Figure 2.
(A) Field dependence of 5 mM cIP 31P R1 in the absence (+) and presence (❍) of 0.5 mg/ml H82C-SL, as well as with both H82C-SL and 5 mM diC7PC (●) in 50 mM HEPES, pH 7.5, with 1 mM EDTA. (B) Field dependence of the cIP 31P R1 with 5 mM diC6PC (❒) or 5 mM PC SUVs (■) and H82C-SL. For comparison the relaxation profile for cIP in buffer is shown (+). The inset in (B) shows the very low field profile for cIP with the PC SUVs and H82C-SL present.
