The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.

Application Abreviews Notes
WB 1/1000 - 1/5000. Detects a band of approximately 110 kDa (predicted molecular weight: 116 kDa).
ICC/IF 1/50 - 1/100.
Flow Cyt 1/10 - 1/100.

ab172730 - Rabbit monoclonal IgG, is suitable for use as an isotype control with this antibody.


IHC-P 1/50 - 1/100. Perform heat mediated antigen retrieval before commencing with IHC staining protocol.
  • Application notes
    Is unsuitable for IP.
  • Target

    • Function
      Addition of nucleotide-activated sugars directly onto the polypeptide through O-glycosidic linkage with the hydroxyl of serine or threonine. Mediates the O-glycosylation of MLL5 and HCFC1. Promotes proteolytic maturation of HCFC1.
    • Tissue specificity
      Highly expressed in pancreas and to a lesser extent in skeletal muscle, heart, brain and placenta. Present in trace amounts in lung and liver.
    • Pathway
      Protein modification; protein glycosylation.
    • Sequence similarities
      Belongs to the O-GlcNAc transferase family.
      Contains 13 TPR repeats.
    • Domain
      The TPR repeat domain mediates recognition of protein substrates.
    • Post-translational
      Ubiquitinated, leading to its proteasomal degradation.
    • Cellular localization
      Cytoplasm. Nucleus. Mostly in the nucleus.

    • ab177941 staining OGT / O-Linked N-Acetylglucosamine Transferase antibody in K562 (human chronic myelogenous leukemia) cells by ICC/IF (Immunocytochemistry/immunofluorescence). Cells were fixed with 4% PFA and permeabilised with 0.1% triton X-100. Samples were incubated with primary antibody at a dilution of 1/500. A goat anti rabbit IgG (Alexa Fluor® 488) (ab150077) was used as the secondary antibody at a dilution of 1/1000. DAPI was used as a nuclear counterstain.
