Background
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.

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.
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.
