Cytokeratin 18 (phospho Ser52) rabbit pAb from ELK Biotechnology Read more ›
Cytokeratin 18 (phospho Ser52) rabbit pAb is a research-use antibody from ELK Biotechnology for studying Cytokeratin 18 in WB, IHC, IF, ELISA workflows with listed reactivity for Human, Rat, Mouse. Specifications and supporting documents below should be reviewed when planning the experiment.
KRT18 encodes the type I intermediate filament chain keratin 18. Keratin 18, together with its filament partner keratin 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],
| Specificity | Phospho-Cytokeratin 18 (S52) Polyclonal Antibody detects endogenous levels of Cytokeratin 18 protein only when phosphorylated at S52. |
