SUMO2/3 Antibody

• Catalog Number: orb248545
• Category: Antibodies
• Description: This antibody reacts with both SUMO2 and SUMO3. The small ubiquitin-related modifier (SUMO) proteins, which include SUMO1, 2 and 3, belong to the ubiquitin-like protein family. Like ubiquitin, the SUMO proteins are synthesized as precursors that undergo processing before conjugation to target proteins. Also, both utilize the E1, E2 and E3 cascade enzymes for conjugation. However, SUMO and ubiquitin differ with respect to targeting. Ubiquitination predominantly targets proteins for degradation, whereas sumoylation targets for a variety of cellular processing, including nuclear transport, transcriptional regulation, apoptosis and protein stability. The unconjugated SUMO1/2/3 proteins localize to the nuclear membrane, nuclear bodies and cytoplasm, respectively. SUMO1 utilizes Ubc9 for conjugation to several targets, which include MDM2, p53, PML and RanGap1. SUMO2/3 contribute to a greater percentage of protein modification than does SUMO1 and they can form polymeric chains. In addition, SUMO3 regulates beta-Amyloid generation and may be critical in the onset or progression of Alzheimer's disease.

• Reactivity: Human
• Immunogen: Recombinant human SUMO2 protein was used as the immunogen for this SUMO2/3 antibody.
• UniProt ID: P55854
• Tested applications: FACS, IF, IHC-P, WB
• Dilution range: Flow cytometry: 1-2ug/million cells,Immunofluorescence: 1-2ug/ml,Western blot: 1-2ug/ml,Immunohistochemistry (FFPE): 1-2ug/ml for 30 min at RT (1) (2)
• Application notes: The concentration stated for each application is a general starting point. Variations in protocols, secondaries and substrates may require the SUMO2/3 antibody to be titered up or down for optimal performance.1. Staining of formalin-fixed tissues requires boiling tissue sections in pH 9 10mM Tris with 1mM EDTA for 10-20 min followed by cooling at RT for 20 minutes.2. The prediluted format is supplied in a dropper bottle and is optimized for use in IHC. After epitope retrieval step (if required), drip mAb solution onto the tissue section and incubate at RT for 30 min.
