Ks 13.1 represents an excellent marker to discriminate non-cornified squamous epithelia from those of different origin.
Polypeptide reacting: Mr 54 000 polypeptide human keratin K13 (formerly designated cytokeratin13; with minor affinity to keratins K14, Mr 50 000, and K16, Mr 48 000 and also to K25, formerly designated K25irs1 from inner root sheath of hair follicle).
Tumors specifically detected: several squamous cell carcinomas, e.g. cervix carcinoma; transitional cell carcinoma of the bladder; craniopharyngioma

Reactivity on cultured cell lines: Cell lines from squamous cell CA, e.g. A-431 from epidermoid CA of vulva; RT 112, RT-4 of urinary bladder
