Comparison of EC₅₀ values as a function of increasing concentration of reactive nitrogen species (RNS). Calibration needs to be performed before each experimental set to determine linear range of detection. CI, confidence interval

Detection method	[RNS]	EC50 a)	95% CIa)	R 2	Linear range of detectiona)
P1–FPs	ONOO−	15.4	13.5–17.5	0.981	≈1–30
P2–FPs	ONOO−	8.3	7.8–8.9	0.994	≈0.5–15
P3–FPs	ONOO−	34.7	33.4–36.0	0.998	≈4–65
