Claudins are a family of proteins that control the flow of molecules in the intercellular space between epithelial cells. They are the most important components of tight junctions--a form of cell-to-cell adhesion that forms continuous seals around cells. Tight junctions act as a physical barrier to prevent solutes and water from passing freely through the paracellular space. Claudins have four transmembrane domains, with the N-terminus and the C-terminus in the cytoplasm. Over 24 members of the claudin family have been identified in humans. In mouse, claudin-1, -2, -6, -7, and -15 are expressed at high levels in liver and kidney, while claudin-5 is expressed in vascular endothelial cells. Knockout mice lacking claudin-2 show defects in the leaky and cation-selective paracellular permeability properties of renal proximal tubules. Claudin-2 is also critical for vitamin D-dependent Ca2+ absorption between enterocytes. Claudin-2 is also known as SP82 and AL022813.
This product is an affinity-purified IgG antibody that recognizes mouse claudin-2 protein. The antibody was raised in rabbit using a synthetic peptide, and can be used for Western blot (WB) detection, immunohistochemical (IHC) detection, and immunocytochemical (ICC) detection of mouse claudin-2 protein.
