The monoclonal antibody LDK18 recognizes human Cytokeratin 18. Cytokeratin 18 is member of the large family of intermediate filaments found within epithelial cells. The family of cytokeratins is made up of type I (acidic) and type II (basic) members which form heterodimers by pairing an acidic with a basic member to compose the keratin filament. Cytokeratin 18 (type I) is most commonly found associated with cytokeratin 8 (type II). Because many tumors of epithelial origin retain expression of keratin proteins, cytokeratin 18 has been used as a tumor marker to identify both tumors and metastases. In addition, cytokeratin 18 has been shown to be expressed in highly proliferative retinal pigment epithelium cells. Applications Reported: This LDK18 antibody has been reported for use in western blotting, microscopy, immunohistochemical staining, and immunocytochemistry. Applications Tested: This LDK18 antibody has been tested by immmunocytochemistry of MeOH-fixed human cells and can be used at less than or equal to 1 µg/mL. It is recommended that the antibody be titrated for optimal performance in the assay of interest. Purity: Greater than 90%, as determined by SDS-PAGE. Aggregation: Less than 10%, as determined by HPLC. Filtration: 0.2 µm post-manufacturing filtered.
