Descrizione generale

Keratin, type II cytoskeletal 7 is a protein encoded by the KRT7 gene in humans. It is also known as cytokeratin-7 (CK-7), keratin-7 (K7), sarcolectin (SCL) and K2C7. Keratin 7 is a type II keratin and is a member of the keratin gene family. It is found on chromosome 12. It is specifically expressed in the simple epithelia lining of the internal organs and in the gland ducts as well as blood vessels.
Monoclonal anti-Cytokeratin Peptide 7 (mouse IgG1 isotype) is derived from the hybridoma produced the fusion of mouse myeloma cells and splenocytes of an immunized mouse. Cytokeratins are the intermediate filaments of endocrine cells. These proteins belongs to the intermediate filament (10 nm) superfamily of cytoskeletal proteins. Cytokeratin 7 (CK 7/ KRT7) is a low molecular weight cytokeratin. It is present in epithelial tissues of lung, breast and ovary.

Specificità

The antibody reacts specifically with most simple epithelia but shows no reaction with epithelial cells in the intestine or in the stomach.

Immunogeno

cytoskeletal preparation of the RT4 human bladder carcinoma cell line.

Applicazioni

Monoclonal Anti-Cytokeratin Peptide 7 antibody produced in mouse has been used in:
  • immunohistochemical staining
  • western blotting
  • immunohistochemistry
  • immunofluorescence.

Azioni biochim/fisiol

Cytokeratins may play an important role in transhepatic transport and canalicular secretion. Cytokeratin 7 (CK 7/ KRT7) only stains bile ducts in normal liver, hence it is considered as “bile duct keratin”. CK 7 is widely used in surgical pathology. It acts as a specific marker for mammary and extramammary Paget′s disease.
