EPR spectra of TEMPONE in suspensions of eggPC liposomes containing Suc (mass ratio of Suc:eggPC = 5:1). The suspensions (10-μL droplets) were dried in the absence (A) or presence (B) of TEMPONE (molar ratio of TEMPONE:eggPC = 1:1). Dry samples without previous TEMPONE (A) were rehydrated in TEMPONE/ferricyanide (1 mm:120 mm; direct) or first in water, followed after a few minutes by TEMPONE/ferricyanide (indirect; final concentration 1 mm:120 mm). Samples with TEMPONE administered before drying (B) were diluted in 300 mm ferricyanide (the nondried and the direct treatment) or first in water for a few minutes followed by 600 mm ferricyanide. The final molar ratio of TEMPONE/ferricyanide was in either case approximately 1:120.
