Technical Data
Cytokeratin 10+13
Cytokeratins are a subfamily of intermediate filament proteins and are characterized by a remarkable biochemical diversity, represented in human epithelial tissues by at least 20 different polypeptides. They range in molecular weight between 40kD and 68kD and isoelectric pH between 4.9 ? 7.8. The individual human cytokeratins are designated 1 to 20. The various epithelia in the human body usually express cytokeratins which are not only characteristic of the type of epithelium, but also related to the degree of maturation or differentiation within an epithelium.Cytokeratin subtype expression patterns are used to an increasing extent in the distinction of different types of epithelial malignancies. The cytokeratin antibodies are not only of assistance in the differential diagnosis of tumors using immunohistochemistry on tissue sections, but are also a useful tool in cytopathology and flow cytometric assays.

Cellular Localization: Cytokeratin 10 is present in keratinising stratified epithelia and in differentiated areas of highly differentiated squamous cell carcinomasCytokeratin 13 is present in non-cornified squamous epithelia except cornea and transitional epithelial regions, with the exception of basal cell layers of some stratified epithelia as well as carcinomas derived from these tissues.

Suitable for use in Flow Cytometry, Western Blot, Immunohistochemistry (Fr) (paraffin-embedded sections) and Immunocytochemistry. Other applications not tested.

Recommended Dilution:
Optimal dilutions to be determined by the researcher.

Storage and Stability:
May be stored at 4C for short-term only. For long-term storage and to avoid repeated freezing and thawing, aliquot Store at -20C. Aliquots are stable for at least 12 months at -20C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.
