Anti-Cytokeratin 10 + 13, clone SPM262

0.2 mg/ml with 0.1 mg/ml BSA (US sourced), 0.05% sodium azide. This antibody recognizes cytokeratin 10 (56.5kDa) and cytokeratin 13 (53kDa) in Western blotting. It recognizes only cytokeratin 13 in formalin-fixed, paraffin-embedded tissue sections. It does not react with cytokeratin 10 positive, cytokeratin 13 negative epithelia such as epidermis. However, on frozen sections this mAb serves as differentiation-related marker of all stratified epithelia, it stains all suprabasal cells in both cornifying and non-cornifying stratified epithelia and more differentiated cells of squamous carcinomas.
