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 kD keratin K8 (originally reported also to 45 kD 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
