W., Dodia C., Feinstein S. USA). MPMVECs were obtained from the Insitute for Environmental Medicine Cell Culture Core and maintained in culture, as described previously (15); these cells had been isolated from C57 BL/6 mice and were used at passage 4. We used the following antibodies: mouse monoclonal anti-p67phox (BD Biosciences San Jose, CA, USA), rabbit polyclonal anti-p47phox (Upstate); mouse monoclonal anti-IgG and monoclonal anti-GAPDH (Santa Cruz Biotechnology, Santa Cruz, CA, USA); polyclonal donkey anti-mouse IR-680 and goat anti-rabbit IR-800Dye secondary antibodies (LI-COR Biosciences, Lincoln, NE, USA); and mouse monoclonal anti-phosphothreonine and rabbit polyclonal anti-phosphoserine (Zymed, South San Francisco, CA, USA). Rabbit polyclonal antibodies to His-tagged human Prdx6, mouse Prdx6, and phosphorylated Prdx6 have been described previously (9, 16). An antibody that reacted specifically to nonphosphorylated Prdx6 was generated by…
