Application Abreviews Notes
WB Use a concentration of 1 µg/ml. Predicted molecular weight: 60 kDa.
ELISA Use at an assay dependent concentration.

  • FunctionOccurs in almost all aerobically respiring organisms and serves to protect cells from the toxic effects of hydrogen peroxide. Promotes growth of cells including T-cells, B-cells, myeloid leukemia cells, melanoma cells, mastocytoma cells and normal and transformed fibroblast cells.
  • Involvement in diseaseDefects in CAT are the cause of acatalasia (ACATLAS) [MIM:115500]; also known as acatalasemia. This disease is characterized by absence of catalase activity in red cells and is often associated with ulcerating oral lesions.
  • Sequence similaritiesBelongs to the catalase family.
  • Post-translational
    The N-terminus is blocked.
  • Cellular localizationPeroxisome.

    Lane 1: Wild-type HAP1 cell lysate (20 µg)
    Lane 2: Catalase knockout HAP1 cell lysate (20 µg)
    Lane 3: HeLa cell lysate (20 µg)
    Lane 4: Jurkat cell lysate (20 µg)

    Lanes 1 - 4: Merged signal (red and green). Green - ab88067 observed at 60 kDa. Red - loading control, ab181602, observed at 37 kDa.
    ab88067 was shown to recognize Catalase when Catalase knockout samples were used, along with additional cross-reactive bands. Wild-type and Catalase knockout samples were subjected to SDS-PAGE. ab88067 and ab181602 (loading control to GAPDH) were diluted at 1 μg/mL and 1/10,000 respectively and incubated overnight at 4°C. Blots were developed with goat anti-rabbit IgG (H + L) and goat anti-mouse IgG (H + L) secondary antibodies at 1/10000 dilution for 1 hour at room temperature before imaging.

  • Overlay histogram showing HeLa cells stained with ab88067 (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 (ab88067, 1µg/1x106 cells) for 30 min at 22ºC. The secondary antibody used was DyLight® 488 goat anti-mouse IgG (H+L) (ab96879) at 1/500 dilution for 30 min at 22ºC. Isotype control antibody (black line) was mouse IgG2a [ICIGG2A] (ab91361, 1µg/1x106 cells) used under the same conditions. Unlabelled sample (blue line). Acquisition of >5,000 events were collected using a 20mW Argon ion laser (488nm) and 525/30 bandpass filter.
