Anti-SUMO2/3 antibody is a SUMO-2/3 mouse monoclonal antibody that is part of the Signal-Seeker™ product line. Anti-SUMO-2/3 mouse monoclonal antibody was raised against full-length recombinant SUMO-2 protein (Uniprot: P61956) combined with a proprietary mix of peptides that include CQIRFRFDGQPINE. The antibody has been shown to recognize a wide range of SUMO-2/3-targeted proteins in HeLa cell lysate (Fig. 1B) and to detect sub-nanogram amounts of recombinant SUMO-2 (Fig. 1A). Epitope mapping has identified that the antibody recognizes a sequence/structure within the peptide CQIRFRFDGQPINE. The peptide sequence is conserved in mammals, birds, and amphibians, giving the antibody broad species reactivity. ASM23 is purified by Protein G affinity chromatography and is supplied as a lyophilized white powder.

Each Lot of antibody is quality controlled to provide a high batch to batch consistency. The Lot specific µg per tube can be found in the Lot specific COA documents.


Figure 2: Immunoprecipitation using SUMO-2/3 Antibody

Denatured cell lysates were prepared from HS43, CT37 and KD S212. 1mg of lysate was used for the immunoprecipitation of SUMO-2/3 conjugates. IP experiments were performed by the protocol presented in IP Method. Western blots of immunoprecipitated proteins were developed using 12F3 (A) or anti-TFII-I antibody (B). (A) Star (*) and circle (o) indicate heavy and light chains of antibodies. Unconjugated free SUMO is denoted by triangle. (B) Unconjugated TFII-I is visible near 120 kDa. Multiple bands indicate that TFII-I is SUMOylated by several SUMO-2/3 proteins.  TFII-I has previously been reported to be a target for Sumoylation .  To see the full Immunoprecipitation protocol, see the product datasheet.

Figure 3: Immunofluorescence of HeLa cells in metaphase with SUMO-2/3 Antibody

HeLa cells were stained and visualized by confocal fluorescence microscopy as described in the IF method below. The cells were stained against α/β-tubulin (sheep anti-tubulin Ab, Cat# ATN02, green) and SUMO-2/3 (12F3, red). DNA was stained with DAPI. Mitotic cells in metaphase were imaged with a Zeiss LSM 780 confocal microscope (1.4 NA 63X objective).  Detection of SUMO 2/3 at chromosomes can be observed during mitosis as has been previously reported10. To see the full Immunofluorescence protocol, see the product datasheet.

Figure 4: Immunofluorescence of HeLa cells in interphase with SUMO-2/3 Antibody

HeLa cells were stained and visualized by widefield fluorescence microscopy as described in the IF method below. The cells were stained against α/β-tubulin (sheep anti-tubulin Ab, Cat# ATN02, green) and SUMO-2/3 (12F3, red). DNA was stained with DAPI. Cells in interphase were imaged with a Zeiss Axio Observer.Z1 microscope (1.4 NA 63X objective). PML nuclear bodies (nuclear dots) were visible in SUMO-2/3 staining as has been previously reported11.  To see the full Immunofluorescence protocol, see the product datasheet.
