Description de la cible

Keratin, type I cytoskeletal 18 (UniProt: P05783; also known as Cell proliferation-inducing gene 46 protein, Cytokeratin-18, CK-18, Keratin-18, K18) is encoded by the KRT18 (also known as CYK18, PIG46) gene (Gene ID: 3875) in human. Cytokeratin-18 (CK-18) is a type I, acidic, intermediate filament protein that is expressed in single-layered epithelial tissues. Its expression is observed in epithelial cells of stomach, duodenum, ileum, colon, placenta, and liver. Higher frequency of CK-18 positivity is observed in adenocarcinomas of the lung, small intestine, prostate, pancreas, and the lymph nodes of breast carcinoma. It forms heteropolymers with its co-expressed complementary type II keratin partner CK-8, which assembles into keratin filaments. It is involved in the uptake of thrombin-antithrombin complexes by hepatic cells. Upon phosphorylation, it plays a role in filament reorganization. It is proteolytically cleaved by caspases during epithelial cell apoptosis and necrosis and this cleavage is shown to occur at Asp-238. Phosphorylation of cytokeratin-18 at serine 33 is shown to increase during mitosis in cultured cells and in regenerating liver. Serine 33 phosphorylation is considered to be essential for its association with 14-3-3 proteins and has a role in keratin organization and distribution. Cytokeratin-18 can undergo O-glycosylation, which results in its increased solubility and reduction in its stability. Mutations in KRT18 gene are known to cause liver cirrhosis characterized by severe panlobular liver-cell swelling with Mallory body formation, prominent pericellular fibrosis, and marked deposits of copper. This ZooMAb recombinant monoclonal antibody, generated by our propriety technology, offers significantly enhanced specificity, affinity, reproducibility, and stability over conventional monoclonals.

Forme physique

Purified recombinant rabbit monoclonal antibody IgG, lyophilized in PBS, 5% Trehalose, normal appearance a coarse or translucent resin. The PBS/trehalose components in the ZooMAb formulation can have the appearance of a semi-solid (bead like gel) after lyophilization. This is a normal phenomenon. Please follow the recommended reconstitution procedure in the data sheet to dissolve the semi-solid, bead-like, gel-appearing material. The resulting antibody solution is completely stable and functional as proven by full functional testing. Contains no biocide or preservatives, such as azide, or any animal by-products. Larger pack sizes provided as multiples of 25 μL.

Reconstitution

300 μg/mL after reconstitution at 25 μL per vial. Please refer to guidance on suggested starting dilutions and/or titers per application and sample type.

Stockage et stabilité

Recommend storage of lyophilized product at 2-8°C; Before reconstitution, micro-centrifuge vials briefly to spin down material to bottom of the vial; Reconstitute each vial by adding 25 μL of filtered lab grade water or PBS; Reconstituted antibodies can be stored at 2-8°C, or -20°C for long term storage. Avoid repeated freeze-thaws.
