Target

  • RelevanceMany cellular proteins, including nuclear pore, oncogene, cytoskeletal, heat shock, viral and transcription regulatory proteins contain single O-linked N-acetylglucosamine (O-GlcNAc) residues attached to serine or threonine residues. It has been observed that O-GlcNAc glycosylated proteins tend to be under phosphorylated relative to unglycosylated proteins and that O-GlcNAc bearing proteins tend to be found in multimeric complexes. This has led to the suggestion that O-GlcNAc glycosylation may obscure phosphorylation sites and acts as a signaling mechanism or mediator of signaling.
  • Alternative names
    • O-GlcNAc antibody

    ICC/IF image of ab2739 stained HeLa cells. The cells were 4% PFA fixed (10 min) and then incubated in 1%BSA / 10% normal Goat serum / 0.3M glycine in 0.1% PBS-Tween for 1h to permeabilise the cells and block non-specific protein-protein interactions. The cells were then incubated with the antibody (ab2739, 10µg/ml) overnight at +4°C. The secondary antibody (green) was Alexa Fluor® 488 Goat anti-Mouse IgG (H+L) used at a 1/1000 dilution for 1h. Alexa Fluor® 594 WGA was used to label plasma membranes (red) at a 1/200 dilution for 1h. DAPI was used to stain the cell nuclei (blue) at a concentration of 1.43µM. This antibody also gave a positive result in 4% PFA fixed (10 min) HEK293, HepG2, and MCF-7 cells at 10µg/ml, and in 100% Methanol fixed (5 min) HeLa, Hek293, HepG2, and MCF-7 cells at 5µg/ml.

    ab2739 staining O-linked N-Acetylglucosamine in HeLa cells treated with tunicamycin from Streptomyces sp (ab120296), by ICC/IF. Decrease in O-linked N-Acetylglucosamine expression correlates with increased concentration of tunicamycin from Streptomyces sp, as described in literature.
    The cells were incubated at 37°C for 24h in media containing different concentrations of ab120296 (tunicamycin from Streptomyces sp) in DMSO, fixed with 100% methanol for 5 minutes at -20°C and blocked with PBS containing 10% goat serum, 0.3 M glycine, 1% BSA and 0.1% tween for 2h at room temperature. Staining of the treated cells with ab2739 (10 µg/ml) was performed overnight at 4°C in PBS containing 1% BSA and 0.1% tween. A DyLight 488 goat anti-mouse polyclonal antibody (ab96879) at 1/250 dilution was used as the secondary antibody. Nuclei were counterstained with DAPI and are shown in blue.

Thank you for the reply and the recommendations. I have one question though. We are not looking for an antibody to detect the enzyme B3GNT6. We are looking to detect core 3 0-glycan(this glycosylation is done by B3GNT6). If I am understanding your emai...
