Technical Data
Claudin 3 (CLDN3)
Tight junctions (TJ) are specialized regions of cell-cell contact that are particularly abundant in luminal epithelial cell sheets. 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. Claudin-3 is expressed in junctions of the duct epithelia and acinar cells as well as uniformly expressed from the periportal to the pericentral hepatocytes in the liver. Also, Claudin-3 was found to be present or secreted by many of the genes up-regulated in ovarian cancer.

Suitable for use in Immunohistochemistry. Other applications not tested.

Recommended Dilution:
Immunohistochemistry: (paraffin-embedded sections). Antigen retrieval by boiling in 10mM sodium citrate (pH 6.0) is needed.
Optimal dilutions to be determined by the researcher.

Posittive Control:

Storage and Stability:
May be stored at 4°C for short-term only. For long-term storage and to avoid repeated freezing and thawing, add sterile 40-50% glycerol, aliquot and store at -20°C. Aliquots are stable for at least 12 months at -20°C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.
