Principle of the Assay: This kit is an Enzyme-Linked Immunosorbent Assay (ELISA). The plate has been pre-coated with Mouse CLDN4 antibody. CLDN4 present in the sample is added and binds to antibodies coated on the wells. And then biotinylated Mouse CLDN4 Antibody is added and binds to CLDN4 in the sample. Then Streptavidin-HRP is added and binds to the Biotinylated CLDN4 antibody. After incubation unbound Streptavidin-HRP is washed away during a washing step. Substrate solution is then added and color develops in proportion to the amount of Mouse CLDN4. The reaction is terminated by addition of acidic stop solution and absorbance is measured at 450 nm.
NCBI and Uniprot Product Information
NCBI Description
The protein encoded by this intronless gene belongs to the claudin family. Claudins are integral membrane proteins that are components of the epithelial cell tight junctions, which regulate movement of solutes and ions through the paracellular space. This protein is a high-affinity receptor for Clostridium perfringens enterotoxin (CPE) and may play a role in internal organ development and function during pre- and postnatal life. This gene is deleted in Williams-Beuren syndrome, a neurodevelopmental disorder affecting multiple systems. [provided by RefSeq, Sep 2013]
Uniprot Description
Claudin-4: Plays a major role in tight junction-specific obliteration of the intercellular space. 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. Belongs to the claudin family.

Product Notes
The Mouse CLDN4 cldn4 (Catalog #AAA1603797) is an ELISA Kit and is intended for research purposes only. The product is available for immediate purchase. The AAA1603797 ELISA Kit recognizes Mouse CLDN4. It is sometimes possible for the material contained within the vial of "Claudin-4 (CLDN4), ELISA Kit" to become dispersed throughout the inside of the vial, particularly around the seal of said vial, during shipment and storage. We always suggest centrifuging these vials to consolidate all of the liquid away from the lid and to the bottom of the vial prior to opening. Please be advised that certain products may require dry ice for shipping and that, if this is the case, an additional dry ice fee may also be required.Precautions
