|Description||Intermediate filaments (IF) are a subset of cytoskeletal proteins which function to give overall structural integrity to the plasma membrane as well as organize cells into specific tissues. IF proteins can be divided into six major types based upon similarity in sequence. Type I and II IF proteins are designated keratins based upon whether they are acidic (I) or basic (II) and are characterized by their remarkable biochemical diversity. A subgroup of keratins, designated cytokeratins, are represented in epithelial tissues by at least 20 different polypeptides, designated 1 to 20. The various epithelia in the human body usually express cytokeratins which are not only characteristic of the type of epithelium, but also related to the degree of maturation or differentiation within an epithelium. Cytokeratin 7 is found in both columnar and glandular epithelium of the lung, cervix, breast, bile ducts, and in the collecting ducts in the kidney as well as mesothelium. The molecular weight of cytokeratin 7 is approximately 54 kDa in SDS/PAGE.|
1. Since applications vary, each investigator should titrate the reagent to obtain optimal results.
2. Please refer to us for technical protocols.
3. Caution: Sodium azide yields highly toxic hydrazoic acid under acidic conditions. Dilute azide compounds in running water before discarding to avoid accumulation of potentially explosive deposits in plumbing.

|Western blot analysis of Cytokeratin 7. Lysate from HeLa cells was probed with anti-cytokeratin 7 (clone RCK105, ABIN967289) at concentrations of 1.0 (lane 1), 0.5 (lane 2), 0.25 µg/ml (lane 3). Cytokeratin 7 is identified as a band of ~55 kDa.|
