31P field cycling profiles for deoxy-diC8PI compounds. Dependence of spin-lattice relaxation rate, R1, on magnetic field for 3 mM l-3-deoxy-diC8PI (●), 3 mM l-3,5-dideoxy-diC8PI (○), and 10 mM diC4PC (Δ) in 50 mM HEPES, pH 7.5, in the field range (A) 0.1 to 11.74 T, and (B) 0.03 to 1 T. (C) R1 for the phosphodiester 31P (●) and phosphate monoester (○) on the inositol C(3) of 0.5 mM d-diC8PI(3)P dissolved in PTEN assay buffer. The solid line indicates the relaxation profile for micellar l-3-deoxy-diC8PI while the dashed line indicates field dependence for the diC4PC monomer.
