Invitrogen™ Cytokeratin 4 Monoclonal Antibody (6B10)

Mouse Monoclonal Antibody

Supplier:  Invitrogen™ MA135558

Catalog No. 01-671-396

Description

The antibody stains non-cornifying squamous epithelium and transitional epithelium of the bladder, cells in certain ciliated pseudo-stratified epithelia and ductal epithelia of various exocrine glands. In immunoblotting experiments the antibody was shown to recognize only cytokeratin no.4 (59 kDa).

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 approximately40 kDa and approximately68 kDa and isoelectric pH between 4. 9-7. 8. The individual human cytokeratins are numbered 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.
