TABLE 2. PQ²⁺uptake by rat brain mitochondria.

Isolated mitochondria (Mito) were incubated in 250 μM PQ²⁺ in the presence of respiration substrates and inhibitors, and intramitochondrial PQ²⁺ concentrations were measured via HPLC. Values are presented as mean ± S.E., n = 3.

Condition	Intramitochondrial PQ²⁺
	μM
Mito + PQ²⁺ + buffer	137.5 ± 50
Mito + PQ²⁺ + buffer + sonication	20 ± 12.5
Mito + PQ²⁺ + buffer + succinate	162.5 ± 75
Mito + PQ²⁺ + buffer + succinate + antimycin A	225 ± 50
Mito + PQ²⁺ + buffer + succinate + FCCP	200 ± 75
