Descrizione generale

Cytokeratin 18 (45 kDa) is the primary type I keratin expressed in simple epithelial cells. Epithelial cells and their derivatives characteristically contain intermediate filaments (IFs) composed of about 20 related polypeptides with molecular weights between 40,000-69,000. Each epithelial tissue has a specific and stable pattern of expression of some of these cytokeratin subunits. Epithelium derived tumors maintain the expression of the cytokeratins found in the normal tissue of origin. Therefore, carcinomas can be identified and classified by immunocytochemical staining with antibodies that react specifically with cytokeratins.
Monoclonal Anti-Cytokeratin Peptide 18 (mouse IgG1 isotype) is derived from the hybridoma produced by the fusion of mouse myeloma cells and splenocytes from an immunized mouse. Cytokeratin 18 (CK18)/keratin 18 is a structural protein and is present in single-layer epithelia. It is located on human chromosome 12q13.

Specificità

The antibody reacts specifically with a wide variety of simple epithelia (e.g. intestine, respiratory and urinary systems, liver, and glandular epithelia). It does not react with stratified squamous epithelia (e.g. esophagus or epidermis) or with non-epithelial cells.

Immunogeno

human epidermal carcinoma A-431 and MCF-7 human breast cancer cell lines.

Applicazioni

Monoclonal Anti-Cytokeratin Peptide 18 antibody produced in mouse has been used in:
  • immunofluorescence
  • fluorescence microscopy
  • confocal fluorescence microscopy
  • immunolabelling
  • histoblots

Azioni biochim/fisiol

Keratins help to maintain structural integrity. They also control Fas?mediated apoptosis and regulate cell size and protein synthesis. Cytokeratin 18 (CK18) plays a major role in the development of lung cancer. It acts as a therapeutic target for non-small cell lung cancer (NSCLC). CK-18 is considered as a promising plasma biomarker to identify patients with HELLP (hemolysis, elevated liver enzymes, low platelets) syndrome.

Micro-computed tomography (µCT) provides non-destructive three-dimensional (3D) imaging of soft tissue microstructures. Specific features in µCT images can be identified using correlated two-dimensional (2D) histology images allowing manual segmentation.
