This antibody reacts with the ~ 22 kDa Claudin-1 protein. Reactivity was confirmed by western blotting and immunofluorescence. Positive controls include MDCK cells (dog), Caco-2cells (human), mouse liver, rat liver, and rat kidney.
NOTE: This antibody strongly cross reacts with the Claudin-3 protein. It has been observed in western blotting inhibition studies using Caco-2 cell lysates, that this antibody is inhibited by addition of Claudin-3 peptide. For a Claudin-1 specific antibody that does not cross-react with Claudin-3, please order Cat. No. 519000 (Rb x Claudin-1) instead.
Claudin-1 is a member of the transmembrane protein family claudins located in cell-cell tight junctions and it acts as a co-receptor for HCV entry into hepatic cells. Claudins are abundant in luminal epithelial sheets where they maintain epithelial cell polarity. Claudin-1 is expressed in most tissues such as bladder, fallopian tube, liver, pancreas, prostate, and skin.
