Epithelial membrane antigen (EMA)
Epithelial membrane antigen (EMA) is a commonly used target for immunohistochemisty, found on the surface of many epithelial cells and thus present in a wide variety of tumors. It also is sometimes seen within the cytoplasm of cells (e.g. perinuclear dot in ependymomas).
