Claudin-1 (In the pipeline)
Claudin-1 is a component of tight junctions which regulates permeability in epithelial and endothelial cell sheets. Anti-Claudin-1 staining localizes to the membrane and is found in almost all carcinomas, which produce a stronger staining intensity than normal tissues. A panel of antibodies against Claudin-1, EMA(+), S-100(-), and GLUT1 is useful for diagnosing perineurioma and neurofibroma. As Claudin-1 is also present in meningiomas, staining for claudin 1, S-100, CD34, EMA, and glial fibrillary acidic protein (GFAP) in concert could be useful in distinguishing meningiomas from histologically similar samples.
