Background
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 cytokeratin 13; 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 CA.

FAQs
The concentration of purified antibodies is mentioned on the datasheet.
For prediluted antibodies the concentration may vary from lot to lot. The concentration of these antibodies is not mentioned on the datasheet and can be requested at support@progen.com.
The supernatant format contains FCS proteins from cell culture medium supplemented with FCS.
The serum antibodies contain other proteins present in serum.
- Supernatant and supernatant concentrate: This format contains hybridoma cell culture supernatant. The antibody is not purified and the antibody concentration is not determined. The antibody concentration may vary from lot to lot. Therefore we recommend to titrate the optimal concentration for the application used for each new lot.
- Lyophilized, purified: This format contains purified antibody in lyophilized form. The reconstitution of this antibody is described in the datasheet. The buffer composition after reconstitution is also mentioned on the datasheet.
- Liquid, purified: This format contains purified antibody in liquid format. The concentration is mentioned on the datasheet.
- Prediluted, purified: This format contains purified antibody in liquid format. Most antibodies in this format are diluted to be ready-to-use for IHC with standard tissue. But some antibodies of this format need further dilution for IHC. This is mentioned on the datasheet.
Most of our liquid antibodies and reconstituted lyophilized antibodies may be stored for short term storage (up to 3 month) at 2-8°C. For long term storage we recommend to store the antibody at -20°C in aliquots. Please avoid freeze and thaw cycles.
Most of our conjugated antibodies should be stored at 2-8°C.
The individual storage conditions are mentioned on the datasheet.
Positive tissue: outer root sheath of hair follicle, sweat gland epithelium on the foot pads, filiform papillae of tongue.
- Homogenization (e.g. with polytron) of tissue samples in buffer L (140 mM NaCl, 5 mM EDTA, 5 mM EGTA, 10 mM Tris-HCl pH7.6) supplemented with protease inhibitors; use 1 ml buffer for approx. 0.1 g tissue.
- To reduce viscosity by high DNA contents, benzonase treatment can be included (30 min at 37°C).
- Centrifugation for 10 min (max. speed, table top centrifuge).
- Resuspend pellet in "Triton extraction buffer" (buffer L plus 1% Triton X-100) using e.g. a dounce homogenizer.
- Centrifugation for 10 min (max. speed, table top centrifuge).
- Resuspend pellet in "high salt extraction buffer" (buffer L plus 1.5 M KCl) using e.g. a dounce homogenizer.
- Centrifugation for 10 min (max. speed, table top centrifuge).
- Resuspend pellet in "Triton extraction buffer" (buffer L plus 1% Triton X-100) using e.g. a dounce homogenizer.
- Centrifugation for 10 min (max. speed, table top centrifuge).
- Resuspend pellet in Laemmli buffer and boil (5 min) for SDS-PAGE.
