Nori Human CLDN1 ELISA Kit
$461.00 – $832.00
This ELISA kit is for quantification of CLDN1 in human. This is a quick ELISA assay that reduces time to 50% compared to the conventional method, and the entire assay only takes 3 hours. This assay employs the quantitative sandwich enzyme immunoassay technique and uses biotin-streptavidin chemistry to improve the performance of the assays. An antibody specific for CLDN1 has been pre-coated onto a microplate. Standards and samples are pipetted into the wells and any CLDN1 present is bound by the immobilized antibody. After washing away any unbound substances, a detection antibody specific for CLDN1 is added to the wells. Following wash to remove any unbound antibody reagent, a detection reagent is added. After intensive wash a substrate solution is added to the wells and color develops in proportion to the amount of CLDN1 bound in the initial step. The color development is stopped, and the intensity of the color is measured.

Background:
Claudin-1 is a protein that is encoded by the CLDN1 gene.[1] It belongs to the group of claudins. The protein is a member of the claudin family and an integral membrane protein and a component of tight junction strands. Loss of function mutations result in neonatal ichthyosis-sclerosing cholangitis syndrome. CLDN1 has been shown to interact with CLDN5[8] and CLDN3.[2] Claudin promotes activation of pro-matrix metalloproteinase-2 mediated by membrane-type matrix metalloproteinases.[3] “Multi-PDZ domain protein 1 (MUPP1) is concentrated at tight junctions through its possible interaction with claudin-1 and junctional adhesion molecule”.
