          Claudin 2 Antibody (51-6100) in ICC/IF

          Immunofluorescence analysis of Claudin-2 was performed using 70% confluent log phase 769-P cells. The cells were fixed with 4% paraformaldehyde for 5 minutes, permeabilized with 0.1% Triton™ X-100 for 10 minutes, and blocked with 2% BSA for 45 minutes at room temperature. The cells were labeled with Claudin 2 Polyclonal Antibody (MH44) (Product # 51-6100) at 1:100 dilution in 0.1% BSA, incubated at 4 degree...

          Product Specific Information

          This antibody is specific for the ~ 22 kDa Claudin-2 protein and does not appear to cross-react with related endogenous proteins. Reactivity was confirmed by western blotting with rat kidney and by immunostaining of rat small intestine. This antibody is confirmed reactive with human, rat, and dog Claudin-2. The reactivity of this antibody with other species has not been determined.

          Target Information

          Tight junctions are specialized regions of cell-cell contact that are particularly abundant in luminal epithelial cell sheets. In freeze-fracture electron micrographs, tight junctions are visualized as belt-like bands of anastomosing sealing strands (TJ strands) that completely encircle the lateral surfaces of each cell. TJ strands on adjacent cells are presumed to interact with each other to form a sort of "molecular gasket" that prevents ions, water and other molecules from leaking between cells and thus, from one side of the sheet to the other. In addition to this so-called "barrier" function, the "fence" function of tight junctions plays an important role in maintaining epithelial cell-polarity by blocking the diffusion of membrane proteins between apical (luminal) and basolateral cell surfaces. Confinement of, for example, the glucose symport to apical surfaces allows glucose to be transported vectorially from the lumen, through the cell, and into the bloodstream. Several peripheral membrane proteins are associated with tight junctions including ZO-1, ZO-2, ZO-3 (members of membrane-associated guanylate-kinase family), cingulin, the 7H6 antigen, Rab-3b, symplekin. While their precise functions are not known, roles for these proteins have been suggested in tight junction assembly and maintenance; signal transduction; and the regulation of tight junction permeability. Furthermore, a growing body of evidence suggests that actin filaments play a major role in regulating tight junction permeability. Until recently, the only transmembrane protein known to be associated with tight junctions was occludin, an ~65 kDa protein with four transmembrane domains. Despite widespread expectation, a critical structural role for occludin in TJ strands was ruled out by the observation of apparently normal tight junctions formed between cells disrupted at both occludin alleles. Fortunately, a closer examination of isolated tight junctions uncovered two related ~22 kDa, four-transmembrane domain proteins, claudin-1 and claudin-2, with no similarity to occludin. In contrast to occludin, which induces only a small number of short strands at cell-cell contact sites when introduced into fibroblasts lacking tight junctions, claudin-1 and -2 induce networks of strands characteristic of true tight junctions. Though inconclusive, these findings suggest that claudin-1 and -2 are major structural components of TJ strands and that occludin plays some other accessory role. Excitement in the tight junction field continues to rise following the recent discovery of claudins -3, -4, -5, -6, -7, and -8 and experiments suggesting that tight junctions in different tissues are comprised of different sets of claudin family proteins. Claudin-1 and claudin-2 connect to the actin cytoskeleton through ZO-1; Claudin-2 functions as a paracellular channel with cation (Na+) selectivity at tight junctions. The expression of claudin-2 is restricted to the liver and kidney, with small amounts also found in the brain.
