|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
| Application Note | Western Blotting: incubate overnight in 4°C. Sample preparation: Resuspend approx. 50 mil. cells in 1 ml cold Lysis buffer (1% laurylmaltoside in 20 mM Tris/Cl, 100 mM NaCl pH 8.2, 50 mM NaF including Protease inhibitor Cocktail). Incubate 60 min on ice. Centrifuge to remove cell debris. Mix lysate with non-reducing SDS-PAGE sample buffer. Application note: Non-reducing conditions. SDS-PAGE (10% separating gel). ELISA: Application note: The antibody C-04 has been tested as the capture antibody in a sandwich ELISA for analysis of Cytokeratin 18 in combination with antibody DA-7 (cat. no. ARG62977) and with the antibody DC-10 (cat. no. ARG53186). * The dilutions indicate recommended starting dilutions and the optimal dilutions or concentrations should be determined by the scientist. |

Bioinformation

|---|---|
| Gene Symbol | KRT18 |
| Gene Full Name | keratin 18, type I |
| Background | Cytokeratin 18, together with its filament partner Cytokeratin 8, are perhaps the most commonly found members 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. [provided by RefSeq, Jul 2008] |
| Function | Cytokeratin 18 involved in the uptake of thrombin-antithrombin complexes by hepatic cells. When phosphorylated, plays a role in filament reorganization. Involved in the delivery of mutated CFTR to the plasma membrane. Together with KRT8, is involved in interleukin-6 (IL-6)-mediated barrier protection. [UniProt] |
| Research Area | Controls and Markers antibody; Signaling Transduction antibody |
| Calculated MW | 48 kDa |
| PTM | Phosphorylation at Ser-34 increases during mitosis. Hyperphosphorylated at Ser-53 in diseased cirrhosis liver. Phosphorylation increases by IL-6. Proteolytically cleaved by caspases during epithelial cell apoptosis. Cleavage occurs at Asp-238 by either caspase-3, caspase-6 or caspase-7. O-GlcNAcylation increases solubility, and decreases stability by inducing proteasomal degradation. |
