Description

General description

Anti-Claudin-1 is produced in rabbit using as immunogen a synthetic peptide corresponding to a sequence located at the C-terminal region of human claudin-1, conjugated to KLH. Claudin-1 (also known as CLDN1, senescence-associated epithelial membrane protein (SEMP1) and ILVASC) is a 22 kDa protein. It is expressed at high levels in kidney and liver and at lower levels in spleen, heart, brain, lung and testis. Claudins are located in both epithelial and endothelial cells in tissues. Claudins consist of four transmembrane domains and two extracellular loops, required to form tight junction strands. CLDN1 gene is located on human chromosome 3q28.

Immunogen

synthetic peptide corresponding to a sequence located at the C-terminal region of human claudin-1, conjugated to KLH. The corresponding sequence is identical in rat claudin-1 and highly conserved (single amino acid substitution) in mouse claudin-1.

Application

Anti-Claudin-1 antibody produced in rabbit has been used in immunohistochemistry and immunoblotting,

Biochem/physiol Actions

Claudin-1 is frequently up-regulated in colorectal carcinomas (CRCs), resulting in tumor differentiation and progression. Defects in the gene encoding claudin-1 are the cause of an autosomal recessive syndrome named ichthyosis-sclerosing cholangitis neonatal (NISCH). It participates in the barrier formation of tight junction. It modulates the tight junctions in human airway epithelium. CLDN1 acts as a receptor for the hepatitis C virus entry.

Physical form
