General description

Monoclonal anti-Cytokeratin Peptide 18 (mouse IgG1 isotype) is derived from the hybridoma produced by the fusion of mouse myeloma cells and splenocytes from an immunized mouse.

Specificity

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.

Immunogen

keratin from the bovine mammary gland epithelial cell line BMGE.

Application

Monoclonal Anti-Cytokeratin Peptide 18 antibody produced in mouse has been used in:
  • immunofluorescence
  • immunoperoxidase staining
  • immunocytochemistry
  • 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.
