General description
The cytokeratins are a family of intermediate filaments found in almost all epithelial cells. They are divided into four subclasses depending on their patterns of reactivity and electrophoretic characteristics and are also arranged I a numbered series of 20 or more acoring to molecular weight and isoelectric point (Quinlan et al. 1985). Types 5 and 6 of cytokeratin (CK5/6) are in high frequency in mesothelial cells, as opposed to cells of adenocarcinoma. CK5/6 has been shown to be a reliable marker for mesothelioma and squamous cell carcinoma of the lung and Bowen′s disease. It does not react with pulmonary adenocarcinoma.
Specificity
Expected to cross-react with mouse and rat.
Reacts with human cytokeratin 5 on immunoblots of cytoskeletal preparations of epidermis and non-cytokeratinizing epithelium (Abstract: European Symposium of the Biology of the Cytoskeleton, Helsinki, 18-21, 6, 89, 1989) and on tissue sections. Shows reactivity with cytokeratin 6 and weak reactivity with cytokeratin 4 on immunoblots. No cross-reactivity with cytokeratins 1, 7, 8, 10, 13, 14, 18 or 19. MAB1620 recognizes basal cells and a part of the stratum spinosum in the normal pavement epithelium. The antibody may be useful for distinction of low differentiated pavement epithelium carcinoma and adenocarcinoma. The antibody works on formalin fixed tissues.
Immunogen
Purified cytokeratin 5 (Exp. Cell Res. (1986) 162:114; J. Invest. Dermatology (1987) 88:191).
Application
Anti-Cytokeratin 5 Antibody, 6, clone D5/16B4 is an antibody against Cytokeratin 5 for use in IF, IH(P) & WB.
Immunohistochemistry (frozen or paraffin sections):
A 1:50-1:100 dilution from a previous lot was used for paraffin, high-temperature antigen retrieval required (Pressure cooker, Citrate/EDTA buffer pH 6.0, 4 minutes at full pressure).
Immunofluorescence:
A previous lot of this antibody was used in Immunofluorescence.
Western blot:
Recognizes a 58kDa and 56kDa band corresponding to cytokeratin 5 and 6.
Optimal working dilutions must be determined by end user.

Post-translational modifications (PTMs) are essential processes conditioning the biophysical properties and biological activities of the vast majority of mature proteins. However, occurrence of several distinct PTMs on a same protein dramatically increases its molecular diversity. The comprehensive understanding of the

Breast adenosquamous carcinomas are rare tumours characterized by well-developed gland formation intimately admixed with solid nests of squamous cells immersed in a highly cellular spindle cell stroma. A low-grade variant has been described that is associated with a better prognosis.
