Clone: LL020
Background: Cytokeratins 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.
Source: LL020 is a Mouse monoclonal IgM antibody derived by fusion of SP2/0-Ag14 murine myeloma cells with spleen cells from a Mouse immunized with a carboxyterminal peptide of Cytokeratin 6.
Specificity: Keratin 6 is specifically found in hyperprolifeRative squamous epithelium such as psoriatic lesions and squamous cell carcinomas, e.g. of the lung. It is expressed in suprabasal Keratinocytes of wounded epidermis, a situation of high cell turnover. LL020 reacts with the basal and suprabasal layers of the entire outer root sheath in normal skin.
Formulation: Each vial contains 100 ul 1 mg/ml purified monoclonal antibody in PBS containing 0.09% sodium azide.
