Keratin 18 is a type I cytokeratin. It is, together with its filament partner keratin 8, perhaps the most commonly found products of the intermediate filament gene family. They are expressed in single layer epithelial tissues of the body. Mutations in this gene have been linked to cryptogenic cirrhosis. Two transcript variants encoding the same protein have been found for this gene.Human keratin 18 and the homologous mouse Endo B are type I IF protein subunits whose expression is restricted in adults to a variety of simple epithelial tissues. Endo B and its coexpressed type II keratin, Endo A (the mouse equivalent of human keratin 8), appear to be the first IF proteins expressed during murine development.
Rat Keratin, type I cytoskeletal 18 (KRT18) ELISA Kit employs a two-site sandwich ELISA to quantitate KRT18 in samples. An antibody specific for KRT18 has been pre-coated onto a microplate. Standards and samples are pipetted into the wells and anyKRT18 present is bound by the immobilized antibody. After removing any unbound substances, a biotin-conjugated antibody specific for KRT18 is added to the wells. After washing, Streptavidin conjugated Horseradish Peroxidase (HRP) is added to the wells. Following a wash to remove any unbound avidin-enzyme reagent, a substrate solution is added to the wells and color develops in proportion to the amount of KRT18 bound in the initial step. The color development is stopped and the intensity of the color is measured.
