  • 靶标

    • 功能Involved in the uptake of thrombin-antithrombin complexes by hepatic cells (By similarity). 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.
    • 组织特异性Expressed in colon, placenta, liver and very weakly in exocervix. Increased expression observed in lymph nodes of breast carcinoma.
    • 疾病相关Defects in KRT18 are a cause of cirrhosis (CIRRH) [MIM:215600].
    • 序列相似性Belongs to the intermediate filament family.
    • 翻译后修饰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-glycosylated at multiple sites; glycans consist of single N-acetylglucosamine residues.

    • ab53118 at 1/50 dilution staining Cytokeratin 18 in human lung carcinoma by Immunohistochemsitry, Paraffin embedded tissue, in the absence or presence of the immunising peptide.
    • ICC/IF image of ab53118 stained HCT116 cells. The cells were 4% formaldehyde fixed (10 min) and then incubated in 1%BSA / 10% normal goat serum / 0.3M glycine in 0.1% PBS-Tween for 1h to permeabilise the cells and block non-specific protein-protein interactions. The cells were then incubated with the antibody (ab53118, 1µg/ml) overnight at +4°C. The secondary antibody (green) was ab96899, DyLight® 488 goat anti-rabbit IgG (H+L) used at a 1/250 dilution for 1h. Alexa Fluor® 594 WGA was used to label plasma membranes (red) at a 1/200 dilution for 1h. DAPI was used to stain the cell nuclei (blue) at a concentration of 1.43µM.

    Thank you for your patience.

    As I mentioned previously, the homology between the immunogen for ab14047 and zebrafish Cytokeratin 18 is 46%. Unfortunately, this is the most homologous antibody we currently have in our catalog. I would not pred...
