Our Abpromise guarantee covers the use of ab76024 in the following tested applications.

The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.

Application Abreviews Notes
WB 1/10000 - 1/20000. Detects a band of approximately 60 kDa (predicted molecular weight: 60 kDa).Can be blocked with Human Catalase peptide (ab225865).
ICC 1/100 - 1/250.
IHC-P 1/100 - 1/250. Perform heat mediated antigen retrieval before commencing with IHC staining protocol.
  • Application notes
    Is unsuitable for Flow Cyt or IP.
  • Target

    • Function
      Occurs 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 disease
      Defects 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 similarities
      Belongs to the catalase family.
    • Post-translational
      The N-terminus is blocked.
    • Cellular localization
    • Information by UniProt

    • Lane 1: Wild type HAP1 whole cell lysate (20 µg)
      Lane 2: CAT knockout HAP1 whole cell lysate (20 µg)
      Lane 3: HeLa whole cell lysate (20 µg)

      Lanes 1 - 3: Merged signal (red and green). Green - ab76024 observed at 60 kDa. Red - loading control, ab9484, observed at 37 kDa.

      ab76024 was shown to specifically react with CAT when CAT knockout samples were used. Wild-type and CAT knockout samples were subjected to SDS-PAGE. Ab76024 and ab9484 (Mouse anti GAPDH loading control) were incubated overnight at 4°C at 5000 dilution and 1/20000 dilution respectively. Blots were developed with Goat anti-Rabbit IgG H&L (IRDye® 800CW) preabsorbed ab216773 and Goat anti-Mouse IgG H&L (IRDye® 680RD) preabsorbed ab216776 secondary antibodies at 1/20000 dilution for 1 hour at room temperature before imaging.

    Thank you for contacting us.

    I would like to apologize for this error. When we received the information, that the antibody has been tested in the laboratory with negative results on rat tissue, we updated immediately the datasheet. This was l...

    The ab16731 is not specific to N-terminal end of the protein. It is produced using recombinant fragment of whole protein and because it is a polyclonal antibody so it will bind to multiple epitopes. It is likely that ab16731 will be able to detect the ...

    Thank you for sending the image which is very self explanatory for multiple bands. Please ignore my suggestions for multiple bands as these were more general rather than related to this case. The antibody (ab98210) I recommended was the second most...
