Application Abreviews Notes
WB 1/1000 - 1/10000. Detects a band of approximately 24-30 kDa (predicted molecular weight: 30 kDa).
Flow Cyt 1/10 - 1/100.

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

 
  • Application notes
    Is unsuitable for ICC,IHC-P or IP.

    • Target

    • Function
      Catalyzes the O-methylation, and thereby the inactivation, of catecholamine neurotransmitters and catechol hormones. Also shortens the biological half-lives of certain neuroactive drugs, like L-DOPA, alpha-methyl DOPA and isoproterenol.
    • Tissue specificity
      Brain, liver, placenta, lymphocytes and erythrocytes.
    • Sequence similarities
      Belongs to the mammalian catechol-O-methyltransferase family.
    • Post-translational
      modifications
      The N-terminus is blocked.
    • Cellular localization
      Cytoplasm and Cell membrane.

        Lane 2: COMT knockout HAP1 whole cell lysate (20 µg)
        Lane 3: A431 whole cell lysate (20 µg)
        Lane 4: MOLT4 whole cell lysate (20 µg)

        Lanes 1 - 4: Merged signal (red and green). Green - ab124813 observed at 28 kDa. Red - loading control, ab18058, observed at 130 kDa.

        ab124813 was shown to recognize COMT when COMT knockout samples were used, along with additional cross-reactive bands. Wild-type and COMT knockout samples were subjected to SDS-PAGE.  Ab124813 and ab18058 (Mouse anti Vinculin loading control) were incubated overnight at 4°C at 1/1000 dilution and 1/10000 dilution respectively. Blots were developed with 800CW Goat anti Rabbit and 680CW Goat anti Mouse secondary antibodies at 1/10000 dilution for 1 hour at room temperature before imaging.
