In Vitro	When POBN (20 mM) and Sodium formate (100 mM) are mixed in the collecting tube with bile in the presence of 2,2′-dipyridyl (DP) (5 mM) and bathocuproinedisulfonic acid disodium salt hydrate (BC) (5 mM), only a minor residual signal of POBN radical adduct is observed[1].
In Vivo	Electron spin resonance (ESR) spectrum of radical adducts detected in bile of rats 1 h after acute Sodium formate (2 g/kg) and POBN (1.5 g/kg) i.p. administration[1]. Animal Model: Fischer male rats (300-400 g)[1] Dosage: 1.5 g/kg (Pharmacokinetic Analysis) Administration: Injected simultaneously i.p. Result: A strong six-line ESR signal of the POBN radical adduct was detected in the bile of rats after acute sodium formate poisoning.
