Human epidermal keratin.
Twenty human keratins are resolved with two-dimensional gel electrophoresis into acidic (pI <5.7) and basic (pI >6.0) subfamilies. The acidic keratins have molecular weights of 56.5, 55, 51, 50, 50', 48, 46, 45, and 40kDa. The basic keratins have molecular weights of 65 - 67, 64, 59, 58, 56 and 52kDa. Members of acidic and basic subfamilies are found together in pairs. The composition of keratin pairs varies with cell type, differentiation status and environment. Many studies have shown the usefulness of keratins as markers in cancer research and tumor diagnosis.
Our Abpromise guarantee covers the use of ab3117 in the following tested applications.
The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
|ICC||Use at an assay dependent dilution.|
|IHC-P||Use at an assay dependent dilution. For staining of formalin-fixed tissues, digest sections with trypsin at 1mg/ml PBS, 10 min at 37°C or Protease XXV at 1mg/ml PBS for 5minutes at 37°C. This antibody is an excellent marker for distinguishing carcinomas from non-epithelial tumours. This antibody used alongside ab9287 has also been used extensively for distinguishing carcinoma from non-carcinoma.|
|IHC-Fr||Use at an assay dependent dilution.|
|Flow Cyt||Use 1µg for 106 cells.|
|ICC/IF||Use a concentration of 5 µg/ml.|
