Our Abpromise guarantee covers the use of ab80676 in the following tested applications.

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

Application Abreviews Notes
ELISA Use at an assay dependent concentration.

ELISA titre using peptide based assay: 1/12500.

WB Use a concentration of 1 µg/ml. Predicted molecular weight: 67 kDa. Good results were obtained when blocked with 5% non-fat dry milk in 0.05% PBS-T.


  • Function
    Catalyzes the initial reaction in O-linked oligosaccharide biosynthesis, the transfer of an N-acetyl-D-galactosamine residue to a serine or threonine residue on the protein receptor. Has a highest activity toward Muc7, EA2 and Muc2, with a lowest activity than GALNT2. Glycosylates 'Thr-57' of SELPLG.
  • Tissue specificity
    Ubiquitous. Highly expressed in mucous cells.
  • Pathway
    Protein modification; protein glycosylation.
  • Sequence similarities
    Belongs to the glycosyltransferase 2 family. GalNAc-T subfamily.
    Contains 1 ricin B-type lectin domain.
  • Domain
    There are two conserved domains in the glycosyltransferase region: the N-terminal domain (domain A, also called GT1 motif), which is probably involved in manganese coordination and substrate binding and the C-terminal domain (domain B, also called Gal/GalNAc-T motif), which is probably involved in catalytic reaction and UDP-Gal binding.
    The ricin B-type lectin domain directs the glycopeptide specificity. It is required in the glycopeptide specificity of enzyme activity but not for activity with naked peptide substrates, suggesting that it triggers the catalytic domain to act on GalNAc-glycopeptide substrates.
