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.
|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.

Immunohistochemical analysis of healthy and colitis mouse colon sections (untreated and treated with enoxaparin) labeling claudin-4 with ab15104 at 1/200. ab7090, anti-rabbit immunoglobulin G conjugated to horseradish peroxidase (HRP) at 1/300 was used as the secondary antibody. ab64238 at 1/50 was used to develop the histological signal.
Antigen retrieval was performed by incubating the sections for 10 minutes at 97°C in 1 mM EDTA buffer, pH 8.0 or 10 mM citrate buffer, pH 6.0.
Control, C; untreated colitis, DSS; oral enoxaparin, OE; intraperitoneal injection of enoxaparin, IPE.

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).
