Clone Host Grade Applications
Polyclonal Rabbit Affinity Purified B IH IF
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.
Claudin-7 is localized in the intercellular junctions of the epithelial cells of the proximal tubules of the nephrons in mammalian kidney1. It is reportedly down regulated in head and neck squamous cell carcinomas2. Claudin-7 is also expressed in normal human and mouse epithelia.
Catalog #C5838-55
ApplicationsSuitable for use in Immunofluorescence, Western Blot and Immunohistochemistry. Other applications not tested.
Recommended DilutionImmunofluorescence (Canine): 1-2ug/ml
Western Blot: 1-2ug/ml
Immunohistochemistry (Human, mouse): 1-2ug/ml. Prior to staining, formalin- xed, paraf n-embedded tissues requires heat-induced epitope retrieval (HIER) with citrate buffer, pH 6.
Optimal dilutions to be determined by the researcher.
