Cytokeratin, Multiple (Biotin)

This is a broad-spectrum antibody which has been reported to differentiate epithelial tumors from non-epithelial tumors. Many studies have shown the usefulness of keratins as markers in cancer research and tumor diagnosis.

Applications: 
Suitable for use in Immunofluorescence, Flow Cytometry, Western Blot, Immunohistochemistry. Other applications not tested.

Recommended Dilution:
Flow Cytometry: 0.5-1ug/million cells 
Immunofluorescence: 0.5-1.0ug/ml 
Western Blot: 0.5-1.0ug/ml
