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 cytokeratin13 with minor affinity to cytokeratins 14, Mr 50 000, and 16, Mr 48 000. Tumors specifically detected: several squamous cell carcinomas, e.g. cervix carcinoma; transitional cell carcinoma of the bladder; craniopharyngioma.

Positive control: Cell lines (tested so far) from squamous cell CA, e.g. A-431 from epidermoid CA of vulva; RT 112, RT-4 of urinary bladder CA.
