AE 3 represents an excellent marker for distinguishing carcinoma from non-epithelial tumors. Tumors specifically detected: all epithelia and their neoplasms.
Polypeptide reacting: Mr 53,000 to Mr 67,000 basic type II keratin polypeptides of human epithelial proteins (keratins - formerly also designated cytokeratins - nos. K1 - K8). Epitope has been mapped to aa 266-299 on alpha-helical rod domain (see Waseem et al., 2004).
Reactivity on cultured cell lines: MCF-7, A-431, RT 112.
