• Product name

    Anti-SUMO4 antibody [EPR7163]
    See all SUMO4 primary antibodies
  • Description

    Rabbit monoclonal [EPR7163] to SUMO4
  • Host species

  • Specificity

    The blast search of immunogen shows high sequence homology with SUMO2 and SUMO3 proteins. Hence ab126606 is more likely to cross react with these proteins however it hasn't been experimentally tested yet.
  • Tested applications

    Suitable for: WB, IP, Flow Cyt, ICC/IFmore details
    Unsuitable for: IHC-P
  • Species reactivity

    Reacts with: Human
  • Immunogen

    Synthetic peptide within Human SUMO4 aa 50-150. The exact sequence is proprietary.

  • Positive control

    • HepG3, 293T and Jurkat whole cell lysate (ab7899); Human spleen tissue lysate; HepG2 cells.

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


ICC/IF 1/250 - 1/500.
  • Application notes
    Is unsuitable for IHC-P.
  • Target

    • Function

      Ubiquitin-like protein which can be covalently attached to target lysines as a monomer. Does not seem to be involved in protein degradation and may modulate protein subcellular localization, stability or activity. Upon oxidative stress, conjugates to various anti-oxidant enzymes, chaperones, and stress defense proteins. May also conjugate to NFKBIA, TFAP2A and FOS, negatively regulating their transcriptional activity, and to NR3C1, positively regulating its transcriptional activity. Covalent attachment to its substrates requires prior activation by the E1 complex SAE1-SAE2 and linkage to the E2 enzyme UBE2I.
    • Tissue specificity

      Expressed mainly in adult and embryonic kidney. Expressed at various levels in immune tissues, with the highest expression in the lymph node and spleen.
    • Sequence similarities

      Belongs to the ubiquitin family. SUMO subfamily.
      Contains 1 ubiquitin-like domain.
    • Post-translational

      In contrast to SUMO1, SUMO2 and SUMO3, seems to be insensitive to sentrin-specific proteases due to the presence of Pro-90. This may impair processing to mature form and conjugation to substrates.

    • Overlay histogram showing HEK293 cells stained with ab126606 (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 (ab126606, 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.
