Immunogen RCK102 is a mouse monoclonal IgG1 antibody derived by fusion of SP2/0 mouse myeloma cells with spleen cells from a mouse immunized with cytokeratins from a human lung cancer cell line (MR21).
Clone RCK102
Isotype IgG1
Specificity Human, mouse, rat, hamster, rabbit, canine, swine.
Purification Purified
Alternative Name Cytokeratin 5+8 / Keratin K5+k8
Background 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.
Application Notes RCK102 is a cytokeratin antibody reacting with cytokeratin 5 and cytokeratin 8. This monoclonal antibody recognizes virtually all epithelial tissues and carcinomas. RCK102 is suitable for immunoblotting, immunocytochemistry, immunohistochemistry on frozen sections and paraffin-embedded tissues and flow cytometry. Optimal antibody dilution should be determined by titration, recommended range is 1:100 - 1:200 for flow cytometry, and for immunohistochemistry with avidin-biotinylated horseradish peroxidase complex (ABC) as detection reagent, and 1:100 - 1:1000 for immunoblotting applications.
