Background Information
Cytokeratin 39 (CK-39) is a member of the cytokeratin family, a group of intermediate filament proteins primarily expressed in epithelial cells. Cytokeratins are classified into Type I (acidic) and Type II (basic) subfamilies, which pair to form heteropolymers essential for maintaining cellular structural integrity, mechanical stability, and stress resistance. CK-39 is predominantly expressed in stratified and glandular epithelia, such as those found in the prostate, bladder, and respiratory tract. Its expression pattern may vary depending on tissue differentiation states.

The species listed in Tested Reactivity are in-house verified and applicable species. For unlisted species, please refer to the homology analysis of the immunogen sequence and related species. For rabbit polyclonal antibodies, homology >70% is recommended. For mouse monoclonal antibodies and rabbit recombinant antibodies, homology >90% is recommended. Generally, the higher the homology, the greater the applicability. However, there will be certain differences in protein expression in different species, tissues or cells. Therefore, the homology analysis results are for reference only and do not serve as a guarantee.
