Cytokeratin 7/13/17/18 Antibody (LdS 23) is a high quality monoclonal Cytokeratin 7/13/17/18 antibody (also designated KRT7 antibody, Keratin 7 antibody, KRT13 antibody, Keratin 13 antibody, KRT17 antibody, Keratin 17 antibody, KRT18 antibody, or Keratin 18 antibody) suitable for the detection of the Cytokeratin 7/13/17/18 protein of human origin. Cytokeratin 7/13/17/18 Antibody (LdS 23) is available as the non-conjugated anti-Cytokeratin 7/13/17/18 antibody. Cytokeratins are a subfamily of intermediate filament keratins that are characterized by a remarkable biochemical diversity, which is represented in human epithelial tissues by at least 20 different polypeptides. Cytokeratins range in isoelectric range between 4.9 and 7.8. Cytokeratin 1 has the highest molecular weight, while Cytokeratin 19 has the lowest molecular weight. The cytokeratins are divided into the type I and type II subgroups. Type II family members comprise the basic to neutral members, Cytokeratins 1-8, while the type I group comprises the acidic members, Cytokeratins 9-20. Various epithelia in the human body usually express cytokeratins which are characteristic of the type of epithelium and related to the degree of maturation or differentiation within said epithelium. Cytokeratin subtype expression patterns are used to an increasing extent in the distinction of different types of epithelial malignancies. Cytokeratin 4 is expressed in differentiated layers of the mucosal and esophageal epithelia along with Cytokeratin 13.
