Description

Description

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 ∽40kDa and ∽68kDa 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.

Description: 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 microscopy, immunohistochemical staining, and immunocytochemistry.Applications Tested: This LDK18 antibody has been tested by immunocytochemistry of MeOH-fixed human cells and can be used at less than or equal to 5 ug/mL. It is recommended that the antibody be carefully titrated for optimal performance in the assay of interest.Excitation: 488 nm; Emission: 519 nm; Laser: Blue Laser.Filtration: 0.2μm post-manufacturing filtered.
