2D immunoblot analysis of Prdx6 forms after paraquat treatment.

<p>Lung protein extracts from <i>Cftr</i>^+/+ and <i>Cftr</i>^−/− mice treated with either paraquat (PQ) or saline (control) were subjected to immunoblot analysis after IEF/SDS-PAGE. Two forms (pI ∼5.9 and ∼6.3) are present in <i>Cftr</i>^+/+ and <i>Cftr</i>^−/− lung treated or not with PQ. An additional form of Prdx6 (pI ∼6.7) is only detected in lung extracts form <i>Cftr</i>^+/+ mice treated with PQ. For both conditions, immunoblots are representative of n = 4 animals of each genotype.
