Application Notes
This O-GlcNAc Antibody (HGAC85) is useful for Western blot, Chromatin Immunoprecipitation, ELISA, Immunocytochemistry/Immunofluorescence, Immunohistochemistry-Paraffin and Immunoprecipitation. ChIP assay reported in literature (PMID: 20368426). ICC and IP reported (Hamiel CR, et al). IHC reported (see Zhang X, et al). In Western blot, this antibody detects several proteins representing O-GlcNAc glycoproteins. Immunofluorescence staining of O-GlcNAc in cells results in labeling of the nuclear envelope and pores, nucleolus, and cytoplasm. This staining pattern is consistent with other methods of detecting O-GlcNAc moieties. DO NOT USE WITH DILUENTS CONAINING GLYCOSYLATED PROTEINS.

Alternate Names for O-GlcNAc Antibody (HGAC85)

  • GlcNAc
  • O-linked N-acetylglucosamine


O-GlcNAc (O-linked N-acetylglucosamine) is one of the most abundant posttranslational modifications on nuclear and cytoplasmic proteins. Many cellular proteins, including nuclear pore, oncogene, cytoskeletal, heat shock, viral and transcription regulatory proteins contain single O-GlcNAc residues attached to serine or threonine residues. This modification occurs via the O-GlcNAc transferase (OGT). There appears to be a competitive modification at these residues. Either the residues are glycosylated or they are phosphorylated. Because of the significance of phosphorylation in cancer research, such competition can be of major interest. O-GlcNAc bearing proteins tend to be found in multimeric complexes. This has led to the suggestion that O-GlcNAc glycosylation may also obscure phosphorylation sites and acts as a signaling mechanism or mediator of signaling. Recent research has revealed that the O-GlcNAcylation of the EGF repeats of Notch are modified via a novel O-GlcNAc transferase, EOGT1 (PMID: 22310717).
