Cytokeratins, a group comprising at least 29 different proteins, are characteristic of epithelial and trichocytic cells. Cytokeratin 5, 6 and 8 are members of the type II neutral-to-basic subfamily.Monoclonal antibodies to cytokeratins are specific markers of epithelial cell differentiation and have been widely used as tools in tumor identification and classification. PCK-26 facilitates the typing of normal, metaplastic and neoplastic cells and it may aid in the discrimination of carcinomas and non-epithelial tumors such as sarcomas, lymphomas and neural tumors. It is also useful in detecting micro-metastases in lymph nodes and other tissues and for determining the origin of poorly differentiated tumors (Lane EB et al,Moll R et al).
Applications:
Suitable for use in Immunofluorescence, Western Blot and Immunohistochemistry (Fr) (paraffin-embedded sections). Other applications not tested.
Recommended Dilution:
Optimal dilutions to be determined by the researcher.
Storage and Stability:
May be stored at 4 degrees C for short-term only. For long-term storage and to avoid repeated freezing and thawing, aliquot Store at -20 degrees C. Aliquots are stable for at least 12 months at -20 degrees C. 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.
