Technical Data
Cytokeratin, Pan
Cytokeratin filaments consist of a complex family of ~20 different cytokeratin polypeptides with relative molecular weights of 40kD to 68kD. These intracellular intermediate filaments of 10nm in diameter provide structural integrity to epithelial cells. All the filament subunits share a general common fibrillar organization, consisting of a central alpha-helical rod that is flanked by N- and C-terminal domains at each end. Generally, low molecular weight keratins are expressed in the early stages of cell development, whereas high molecular weight keratins are expressed in maturing cells.

Suitable for use in Immunohistochemistry. Other applications not tested.

Recommended Dilutions:
Immunohistochemistry (Frozen, paraffin): 1:75-1:200 for paraffin. Incubate 30-60 minutes at RT. Requires Proteolytic enzymatic pretreatment.
Optimal dilutions to be determined by the researcher.
