Target

  • Relevance
    Many 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.

    ab2739 stained in MCF7cells. Cells were fixed with 4% paraformaldehyde (10min) at room temperature and incubated with PBS containing 10% goat serum, 0.3 M glycine, 1% BSA and 0.1% triton for 1h at room temperature to permeabilise the cells and block non-specific protein-protein interactions. The cells were then incubated with the antibody ab2739 at 5µg/ml and ab6046 (Rabbit polyclonal to beta Tubulin - Loading Control) at 1/1000 dilution overnight at +4°C. The secondary antibodies were ab150080 (pseudo-colored red) and ab150117 (colored green) used at 1 ug/ml for 1hour at room temperature. DAPI was used to stain the cell nuclei (colored blue) at a concentration of 1.43µM for 1hour at room temperature.

    Jurkat cells were treated with either 50 uM PugNAc (ab144670) or 4 mM glucosamine + 50 uM PugNAc (ab144670) for three hours prior to harvest to stimulate O-linked glycosylation. The expected increase in glycosylation is observed in the treated lanes 2 & 4.

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...

You are correct that the uniprot link in the previous email (Uniprot: http://www.uniprot.org/uniprot/Q6ZMB0http://www.uniprot.org/uniprot/Q6ZMB0) is for the core 3 synthase, which is B3GNT6. Inferring from the alternative names for this synthase (Beta-...
