Additional Information

Alternative name: Cytokeratin 18 / Keratin K18

Immunogen: RGE53 is a mouse monoclonal IgG1 antibody derived by fusion of mouse myeloma cells with spleen cells from a mouse immunized with a cytoskeletal preparation of cells.

Format: Culture supernatant

Isotype: IgG1  (Matching secondary antibodies)

Clone: RGE53

Description: 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 40 kDa and 68 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.

Specificity: Human, mouse, rat, hamster, rabbit, chicken, canine and swine.

Application Details

Application Notes: RGE53 reacts exclusively with cytokeratin 18 which is present in glandular epithelial cells of the digestive, respiratory, and urogenital tracts, endocrine and exocrine cells and mesothelial cells, as well as adenocarcinomas originating from them. RGE53 is suitable for immunoblotting, immunocytochemistry, immunohistochemistry on frozen sections and for immunohistochemistry with avidin-biotinylated horseradish peroxidase complex (ABC) as detection reagent and for flow cytometry. Optimal antibody dilution should be determined by titration.

Storage: Store at 4 o C, or in small aliquots at -20 o C.

Restrictions: For Research Use only
