Our Abpromise guarantee covers the use of ab58744 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
WB Use a concentration of 2.5 µg/ml. Detects a band of approximately 41 kDa (predicted molecular weight: 50 kDa). Good results were obtained when blocked with 5% non-fat dry milk in 0.05% PBS-T.
IHC-P Use a concentration of 4 - 8 µg/ml.


  • Tissue specificityExpressed in some epidermal sweat gland ducts (at protein level) and in exocervix, esophagus and placenta.
  • Involvement in diseaseDefects in KRT13 are a cause of white sponge nevus of cannon (WSN) [MIM:193900]. WSN is a rare autosomal dominant disorder which predominantly affects non-cornified stratified squamous epithelia. Clinically, it is characterized by the presence of soft, white, and spongy plaques in the oral mucosa. The characteristic histopathologic features are epithelial thickening, parakeratosis, and vacuolization of the suprabasal layer of oral epithelial keratinocytes. Less frequently the mucous membranes of the nose, esophagus, genitalia and rectum are involved.
  • Sequence similaritiesBelongs to the intermediate filament family.
  • Post-translational
    O-glycosylated; glycans consist of single N-acetylglucosamine residues.
