keratin from the bovine mammary gland epithelial cell line BMGE.


The antibody reacts with a wide variety of simple epithelia (gastrointestinal, respiratory, urinary, liver, and glandular) but does not react with most stratified squamous epithelium (esophagus, epidermis) or non-epithelial cells.


Monoclonal Anti-Cytokeratin Peptide 18 antibody produced in mouse is suitable for the following applications:
• immunohistochemistry (using formalin-fixed, paraffin-embedded sections)
• indirect immunofluorescence: at a working dilution of 1:100 using formalin-fixed, paraffin-embedded sections of human tissue
• microarray

Biochem/physiol Actions

Cytokeratins are proteins of keratin-containing intermediate filaments that provide mechanical support and other additional functions in epithelial cells. It is found in the intracytoplasmic cytoskeleton of epithelial tissue. Epithelial tissue expresses cytokeratin subunits in a specific and stable pattern. Cytokeratins along with vimentin are involved in cell proliferation, migration and differentiation of preodontoblasts and preameloblasts. The intermediate-sized filaments are abundant in human endothelial cells and are mostly of vimentin type.
