Immunogen OVTL12/30 is a mouse monoclonal IgG1/kappa antibody derived by fusion of SP2/0-Ag14 mouse myeloma cells with spleen cells from a mouse immunized with a cytoskeletal preparation of OTN-11 ovarian carcinoma cell line.
Clone OVTL12-30
Isotype IgG1
Specificity Human exclusively.
Purification Purified
Alternative Name Cytokeratin 7 / Keratin K7 (KRT7 Antibody Abstract)
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 OVTL12/30 reacts exlcusively with cytokeratin 7 which is present in specific glandular-type epithelia and most carcinomas derived thereof. OVTL12/30 is effective on frozen tissue after fixation in methanol. It is particularly effective on paraffin-embedded tissue, for which pretreatment with e.g. 0.1% pronase / 0.1% trypsine in PBS or 0.5% pepsine in 0.01N HCl or microwave pretreatment is required. In addition, OVTL 12/30 is suitable for immunocytochemistry, immunoblotting 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.
Restrictions For Research Use only
Storage 4 °C
