9E12C72_PURE_Claudin-1_Antibody_051017
Total cell lysates (15 µg protein) from 293T (negative control), A431 and NIH3T3 cells were resolved by 4-12% Bis-Tris gel electrophoresis, transferred to nitrocellulose, and probed with 2 µg/mL purified anti-Claudin-1 (clone 9E12C72) antibody, competitor’s antibody used at manufactures recommended concentration (upper). Proteins were visualized by chemiluminescence detection using a goat anti-mouse-IgG secondary antibody conjugated to HRP for anti-Claudin-1 antibody, and a donkey anti-rabbit IgG Antibody conjugated to HRP for competitor’s antibody. Direct-Blot™ HRP anti-β-actin Antibody was used as a loading control (lower). Lane M: molecular weight ladder and M* indicates extended exposure of the molecular weight ladder.

Description

Claudin-1 is a member of the claudin family of proteins, which is composed of at least 24 members. Claudin proteins are integral membrane proteins with 4 transmembrane regions and 2 extracellular loops that form tight junctions. Tight junctions function as a channel and a barrier to maintain cellular morphology, polarity, and homeostasis between epithelial cells. Claudin-1 is a main component of tight junctions and is sorely responsible for normal barrier function of the skin. Misregulated expression of Claudin-1 has been shown to be associated with cancer progression and metastasis in several cancers. Claudin-1 has been found to be overexpressed in neoplasia associated with inflammatory bowel disease. Mutations in Claudin-1 gene lead to human skin diseases and Claudin-1 deficient mice die soon after birth due to dehydration.
