Our Abpromise guarantee covers the use of ab203570 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
ICC/IF Use a concentration of 4 - 6 µg/ml.
Flow Cyt Use at an assay dependent concentration.

Use at 0.5-1 µg/test

IHC-P Use a concentration of 4 - 6 µg/ml. Perform heat mediated antigen retrieval with Tris/EDTA buffer pH 9.0 before commencing with IHC staining protocol.
WB Use a concentration of 2 - 3 µg/ml. Predicted molecular weight: 11 kDa.


  • Function

    Ubiquitin-like protein which can be covalently attached to target lysines either as a monomer or as a lysine-linked polymer. Does not seem to be involved in protein degradation and may function as an antagonist of ubiquitin in the degradation process. Plays a role in a number of cellular processes such as nuclear transport, DNA replication and repair, mitosis and signal transduction. Covalent attachment to its substrates requires prior activation by the E1 complex SAE1-SAE2 and linkage to the E2 enzyme UBE2I, and can be promoted by an E3 ligase such as PIAS1-4, RANBP2 or CBX4.
  • Tissue specificity

    Expressed predominantly in liver.
  • Sequence similarities

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

    Polymeric chains can be formed through Lys-11 cross-linking.
    Cleavage of precursor form by SENP1, SENP2 or SENP5 is necessary for function.

  • Immunohistochemical analysis of formalin fixed, paraffin embedded Human colon carcinoma tissue labeling Sumo 3 using ab203570 at 5 μg/mL, followed by DAB detection.

  • Immunofluorescent analysis of U2OS cells labeling Sumo 3 using ab203570 at 5 μg/mL (left image). Right image: sample with immunogenic phosphopeptide. Alexa Fluor® 488 Goat anti-Rabbit at 1/1000 dilution was used as secondary antibody.

  • Flow cytometric analysis of fixed and permealized Jurkat cells labeling Sumo 3 using ab203570 at 0.5 μg/test (Black) followed by secondary detection with Alexa Fluor® 488 Goat anti-Rabbit. Cells incubated without primary antibody (grey) for control. Preincubation with immunizing peptide decreased the staining (red).
