WB Use a concentration of 5 µg/ml. Detects a band of approximately 65 kDa (predicted molecular weight: 60 kDa).


  • 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.

    Performed under reducing conditions.

    Exposure time : 10 seconds
  • ICC/IF image of ab15834 stained human HeLa cells. The cells were methanol fixed (5 min) and incubated with the antibody (ab15834, 5µg/ml) for 1h at room temperature. The secondary antibody (green) was Alexa Fluor® 488 goat anti-rabbit IgG (H+L) used at a 1/1000 dilution for 1h. Image-iTTM FX Signal Enhancer was used as the primary blocking agent, 5% BSA (in TBS-T) was used for all other blocking steps. DAPI was used to stain the cell nuclei (blue). Alexa Fluor® 594 phalloidin was used to label F-actin (red).

  • Immunofluorescence analysis of SH-SY5Y cells, staining Catalase with ab15834.

    Cells were fixed with paraformaldehyde and permeabilized with 0.25% Triton-X in PBS, followed by incubation with primary antibody on a shaker at 4°C overnight. A fluorescently labeled goat anti-rabbit IgG (diluted 1/1000) was used as the secondary antibody

Thank you for contacting us. The specific band for this antibody is typically observed around 65 kDa and the protein sequence does not suggest any isoforms or processing that would result in a specific 32 kDa band. I would suggest running a positive co...
