Our Abpromise guarantee covers the use of ab15104 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 1 µg/ml. Detects a band of approximately 20 kDa (predicted molecular weight: 22 kDa).
ICC/IF Use at an assay dependent concentration.
IHC-P 1/200. Perform heat mediated antigen retrieval before commencing with IHC staining protocol.


  • FunctionPlays a major role in tight junction-specific obliteration of the intercellular space.
  • Involvement in diseaseNote=CLDN4 is located in the Williams-Beuren syndrome (WBS) critical region. WBS results from a hemizygous deletion of several genes on chromosome 7q11.23, thought to arise as a consequence of unequal crossing over between highly homologous low-copy repeat sequences flanking the deleted region.
  • Sequence similaritiesBelongs to the claudin family.
  • Cellular localizationCell junction > tight junction. Cell membrane.

  • Anti-Claudin 4 antibody (ab15104) at 1 µg/ml + SHSY-5Y (Human neuroblastoma cell line) Whole Cell Lysate at 10 µg

    Goat Anti-Rabbit IgG H&L (HRP) preadsorbed (ab97080) at 1/5000 dilution
    Developed using the ECL technique

    Performed under reducing conditions.

    Predicted band size : 22 kDa
    Observed band size : 20 kDa (why is the actual band size different from the predicted?)
    Additional bands at : 125 kDa,34 kDa,35 kDa. We are unsure as to the identity of these extra bands.

    Exposure time : 30 seconds
  • Formalin fixed paraffin embedded human tonsil stained with ab15104 (1:200, 10 min at room temperature).
