Cytokeratin 18/19 antibody
Human anti Human cytokeratin 18/19 antibody recognizes human cytokeratin 18, a amino acid type I intermediate filament protein expressed by epithelial cells. The intermediate filaments are expressed as heterodimers in epithelial tissues. Cytokeratin 18 (CK18) is often co-expressed with cytokeratin 8 (CK8). The CK18/CK8 heterodimer is the major cytokeratin pair found in simple epithelia such as that found in the liver, intestine and breast ducts. CK18 plays an important role in maintaining epithelial cell integrity.
This clone has also been demonstrated to cross-react with cytokeratin 19. Human anti Human cytokeratin 18/19 antibody recognizes cytokeratin 18 as a band of ~48 kDa and cytokeratin 19 as a band of ~44 kDa in western blotting under reducing conditions.
