Long descriptionCytokeratins are a subfamily of intermediate filament proteins and are characterized by a remarkable biochemical diversity, represented in 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 Cytokeratin polypeptides 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.
Antibody come fromM20 is a Mouse monoclonal IgG1 antibody derived by fusion of murine myeloma cells with spleen cells from a Mouse immunized with Keratin isolated from the Human breast carcinoma cell line MCF-7.
Other descriptionEach vial contains 100 ul 1 mg/ml purified monoclonal antibody in PBS containing 0.09% sodium azide.

Antibody's specificityM20 reacts with glandular epithelial cells (endocrine and exocrine) as well as mesothelial cells and epithelia of the digestive, respiRatory and urogenital tract. Also most adenocarcinomas derived from these cells are positive. The M20 epitope has been mapped to amino acids 353-367 on the alpha helical rod domain of Cytokeratin 8 (see reference 10).
Research interestCytoskeleton
ApplicationFlow Cytometry,Immunocytochemistry,Immunohistochemistry (frozen),Immunohistochemistry (paraffin),Western blotting
Antibody's suited forM20 is suitable for immunoblotting, immunocytochemistry, immunohistochemistry on frozen and paraffin-embedded tissues and flow cytometry. Optimal antibody dilution should be determined by titration; recommended range is 1:100 – 1:200 for immunohistochemistry with avidin-biotinylated Horseradish peroxidase complex (ABC) as detection reagent, and 1:100 – 1:1000 for immunoblotting applications.
StorageStore at 4°C, or in small aliquots at -20°C.

DescriptionThis antibody needs to be stored at + 4°C in a fridge short term in a concentrated dilution. Freeze thaw will destroy a percentage in every cycle and should be avoided.
TestMouse or mice from the Mus musculus species are used for production of mouse monoclonal antibodies or mabs and as research model for humans in your lab. Mouse are mature after 40 days for females and 55 days for males. The female mice are pregnant only 20 days and can give birth to 10 litters of 6-8 mice a year. Transgenic, knock-out, congenic and inbread strains are known for C57BL/6, A/J, BALB/c, SCID while the CD-1 is outbred as strain.
