The antibody recognizes all simple epithelia including glandular epithelia. It does not react with stratified squamous epithelium. Useful for the differentiation between carcinomas and lymphomas. In immunoblotting (Western) NCL 5D3 is directed against the the 52.2 kDa keratin K8 (originally reported also to 45 kDa keratin K18; formerly also designated cytokeratins according to the Moll-catalogue). Epitope has been mapped to aa 353-367 on alpha helical rod domain of keratin K8 (Waseem et al., 2004).
Positive control: glandular epithelium.

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 email@example.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.
