General description

Cytokeratin is a 52.5kD cytoplasmic structural protein that belongs to type II, neutral-to-basic subfamily. It consists of 29 different proteins which is the characteristic of epithelial and trichocytic cells. Monoclonal anti-cytokeratin peptide 8 antibody can be used as a marker for epithelial cell differentiation as well as a tool for tumor identification and classification. It can also be used in western blotting. Mouse anti-cytokeratin peptide 8 antibody reacts specifically with various human simple and complex epithelia like- liver, intestine, pancreas, urinary bladder, salivary gland, thyroid, prostate, mesothel, and placenta but not with stratified squamous epithelia. The product also does not react with non-epithelial tissues (exceptions-certain smooth muscle cells). This product has also shown cross reactivity for cytokeratin of rabbit, cow, dog, and cat.


Monoclonal anti-cytokeratin peptide 8 antibody (diluted 1:100 in PBS) can be used in immunofluorescence microscopy. It can also be used to localize cytokeratin 8 by using many immunochemical assays like immunohistochemistry, immunoblotting and dot blotting.
