Target

  • Relevance

    Function: Together with KRT19, helps to link the contractile apparatus to dystrophin at the costameres of striated muscle. Tissue specificity: Observed in muscle fibers accumulating in the costameres of myoplasm at the sarcolemma membrane in structures that contain dystrophin and spectrin. Expressed in gingival mucosa and hard palate of the oral cavity. Disease: Cirrhosis Similarity: Belongs to the intermediate filament family. PTM: Phosphorylation on serine residues is enhanced during EGF stimulation and mitosis. Ser-74 phosphorylation plays an important role in keratin filament reorganization. O-glycosylated. O-GlcNAcylation at multiple sites increases solubility, and decreases stability by inducing proteasomal degradation. O-glycosylated (O-GlcNAcylated), in a cell cycle-dependent manner.

  • Overlay histogram showing MCF7 cells stained with ab17139 (red line). The cells were fixed with 80% methanol (5 min) and then permeabilized with 0.1% PBS-Tween for 20 min. The cells were then incubated in 1x PBS / 10% normal goat serum / 0.3M glycine to block non-specific protein-protein interactions. The cells were then incubated with the antibody (ab17139, 1/100 dilution) for 30 min at 22ºC. The secondary antibody used was DyLight® 488 goat anti-mouse IgG (H+L) (ab96879) at 1/500 dilution for 30 min at 22ºC. Isotype control antibody (black line) was mouse IgG1 [ICIGG1] (ab91353, 2µg/1x106 cells ) used under the same conditions. Acquisition of >5,000 events was performed. This antibody gave a positive signal in MCF7 cells fixed with 4% paraformaldehyde (10 min)/permeabilized in 0.1% PBS-Tween used under the same conditions.

Cells were fixed in paraformaldehyde and permeabilized in 0.1% Triton X-100 prior to blocking in 1% BSA for 1 hour at room temperature. The primary antibody was diluted 1/1000 and incubated with the sample for 1 hour at room temperature. The secondary antibody was Alexa Fluor 488®-conjugated Goat anti-Mouse, diluted 1/1000.

Answer

Thank you for your enquiry.

I would like to reassure you that our antibodies have all been tested successfully and would be covered by our guarantee in the applications listed on the datasheets. Therefore, any Cytokeratin 8+18 antibody- antibody tested in the species and application you are using should be suitable for your applications.

Also, although we produce many in-house antibodies, we obtain other antibodies from a wide range of sources. Therefore, comparison experiments will not often have been done.

If you wish to be more certain, I can suggest choosing the antibody that has been best characterized. By this I mean the antibody that has been tested in the most applications and has the most data available (on the datasheet).

Taking this into consideration, my recommendations would be ab17139 or ab15224.
