Validation:

Independent Antibody Validation in Cell lines (Figure 1) shows similar CLAUDIN4 expression profile in human cell lines detected by two independent anti-CLAUDIN4 antibodies that recognize different epitopes, 7025 against C-terminus domain and 24-028 against C-terminus domain.  CLAUDIN4 proteins are detected in the most tested cell lines at different expression levels by the two independent antibodies. 

Isoform: Human CLAUDIN4 has one isoform (209aa, 22kD) . Mouse CLAUDIN4 has one isoform (210aa, 22kD) and Rat CLAUDIN4 also has one isoform (210aa, 22kD) . 7025 can detect human, mouse and rat.

BACKGROUND: CLAUDIN4 Antibody: CLAUDIN4 is an integral membrane protein belonging to the claudin family, a family of cellular adhesion molecules that are components of tight junctions. CLAUDIN4 is a component of tight junction strands and may play a role in internal organ development and function during pre- and postnatal life. The CLAUDIN4 gene is deleted in Williams-Beuren syndrome, a neurodevelopmental disorder affecting multiple systems. CLAUDIN4 is frequently overexpressed in ovarian and other epithelial cancers.
