ab172730 - Rabbit monoclonal IgG, is suitable for use as an isotype control with this antibody.

  • Application notes
    Is unsuitable for IHC-P.
  • Target

    • Function

      Involved in redox regulation of the cell. Reduces peroxides with reducing equivalents provided through the thioredoxin system. It is not able to receive electrons from glutaredoxin. May play an important role in eliminating peroxides generated during metabolism. Might participate in the signaling cascades of growth factors and tumor necrosis factor-alpha by regulating the intracellular concentrations of H(2)O(2).
    • Sequence similarities

      Belongs to the ahpC/TSA family.
      Contains 1 thioredoxin domain.

    • Lane 1: Wild-type HAP1 cell lysate (20 µg)
      Lane 2: Peroxiredoxin 2/PRP knockout HAP1 cell lysate (20 µg)
      Lane 3: HeLa cell lysate (20 µg)
      Lane 4: LnCaP cell lysate (20 µg)
      Lanes 1 - 4: Merged signal (red and green). Green - ab133481 observed at 24 kDa. Red - loading control, ab8245, observed at 37 kDa.
      ab133481 was shown to specifically react with Peroxiredoxin 2/PRP when Peroxiredoxin 2/PRP knockout samples were used. Wild-type and Peroxiredoxin 2/PRP knockout samples were subjected to SDS-PAGE. ab133481 and ab8245 (loading control to GAPDH) were diluted 1/50 000 and 1/10 000 respectively and incubated overnight at 4°C. Blots were developed with Goat anti-Rabbit IgG H&L (IRDye® 800CW) preadsorbed (ab216773)
      and Goat anti-Mouse IgG H&L (IRDye® 680RD) preadsorbed (ab216776) secondary antibodies at 1/10000 dilution for 1 h at room temperature before imaging.

    • Overlay histogram showing HeLa cells stained with ab133481 (red line). The cells were fixed with 80% methanol (5 min) and then permeabilized with 0.1% PBS-Tween for 20 min. The cells were then incubated in 1x PBS / 10% normal goat serum / 0.3M glycine to block non-specific protein-protein interactions followed by the antibody (ab133481, 1/1000 dilution) for 30 min at 22°C. The secondary antibody used was Alexa Fluor® 488 goat anti-rabbit IgG (H&L) (ab150077) at 1/2000 dilution for 30 min at 22°C. Isotype control antibody (black line) was rabbit IgG (monoclonal) (0.1μg/1x106 cells) used under the same conditions. Unlabelled sample (blue line) was also used as a control. Acquisition of >5,000 events were collected using a 20mW Argon ion laser (488nm) and 525/30 bandpass filter.
