Manufactured in: United Kingdom Cytokeratin 9 (47-59) is derived from the cytoskeleton component cytokeratin, a family of intermediate filamentous proteins which have structural and mechanical functions in the cell. The cytokeratin family contains cytokeratins 1-20, where cytokeratins 1-8 are categorised as being type II basic, while cytokeratins 9-20 are categorised as being type I acidic. Cytokeratins 1 to 20 have been ordered regarding their molecular weight, where cytokeratin 1 has the highest molecular weight and cytokeratin 20 has the smallest.
The expression of Cytokeratins in the epithelial tissues is dependent on where it is located in the body and at which stage of differentiation and development the organism is at. Consequently cytokeratins can be used as tissue specific markers (for example an ocular surface epithelia marker) and to investigate cell differentiation progression.
The arginine residue at position 13 is isotopically labelled with carbond-13 (6) and nitrogen-15 (4).
