Representative SR signals with fitted curves and residuals (the experimental signal minus the fitted curve) for 7-SASL (A) and ASL (B) from cortical intact membranes. Signals were recorded at 37°C for deoxygenated samples (equilibrated with 100% nitrogen) and equilibrated at 37°C with an air/nitrogen gas mixture. For deoxygenated samples the SR signals can be satisfactorily fitted with only a double-exponential function: for 7-SASL, with time constants of 6.18 ± 0.43 µs and 2.82 ± 0.11 µs, and for ASL, with time constants of 4.80 ± 0.39 µs and 1.89 ± 0.07 µs. The first residual is for single- and the second residual for double-exponential fits. The SR signal in the presence of molecular oxygen can be fitted satisfactorily only with a double-exponential function: for 7-SASL, with time constants of 3.11 ± 0.17 µs and 1.44 ± 0.06 µs, and for ASL, with time constants of 4.47 ± 0.31 µs and 0.98 ± 0.05 µs. The third residual is for single- and the fourth residual for double-exponential fits.
