Anti-Keratin K3/K76 Antibody, clone AE5

Cytokeratin 3, also known as 65kDa Cytokeratin or Keratin K3 is a specific keratin found primarily in the corneal epithelium and minorly in other epithelium like that of the esophagus. The corneal epithelium tissue forms the outermost layer of the cornea, which is the clear front covering of the eye. Keratins are divided into two primary types based upon their isoelectric mobility and size, acidic, or type 1:40-55kDa, and basic to neutral or type 2, 56-70kDa. Cytokeratin 3 is a type II cytokeratin. Type II cytokeratins form pairs with other cytokeratins. Cytokeratin 3 is expressed in the corneal epithelium with Cytokeratin 12. Together Cytokeratin 3 and Cytokeratin 12 form molecules known as intermediate filaments. These filaments assemble into strong networks that provide strength and resilience to the corneal epithelium. Mutations in Cytokeratin 3 have been associated with Meesmann′s Corneal Dystrophy a disease characterized by fragility of the anterior corneal epithelium.

This Anti-Keratin K3/K76 Antibody, clone AE5 is validated for use in Western Blotting and Immunohistochemistry and Immunofluorescence for the detection of Keratin K3/K76.

Immunohistochemistry Analysis: A 1:1000 dilution from a representative lot detected Keratin K3/K76 in bovine cornea epithelial cells.
Immunohistochemistry Analysis: A representative lot was used by an independent laboratory in Keratin 3 expressed epithelial cells on the surface of submerged and AL explants, indicating that they were derived from limbal progenitor cells via migration. (Kawakita, T., et al. (2005) Am J Pathol, 167:381-93.).
Western Blotting Analysis: A representative lot was used by an independent laboratory in Rabbit epithelial Keratin lysate. (Schermer, A, et al. (1986) J. Cell Biol., 103: 49-62).
Western Blotting Analysis: A representative lot was used by an independent laboratory in rabbit corneal tissue lysate. (Cooper, D., et al. (1986) J. Biol. Chem., 261: 4646-54).
Immunocytochemistry Analysis: A representative lot was used by an independent laboratory in human limbal stem cells cultured in medium supplemented with human EGF. (Sharifi, A.M., et al. (2010) Biocell. 34(1):53-55).
Immunofluorescence Analysis: A representative lot was used by an independent laboratory in rabbit corneal and limbal tissues, limbal explant, and epithelial outgrowth on human AM. (Wang D.Y., et al. (2003) Invest Ophthalmol Vis Sci. 44(11):4698-704).
Immunofluorescence Analysis: A representative lot was used by an independent laboratory inRabbit corneal epithelial Keratin cells. (Schermer, A, et al. (1986) J. Cell Biol., 103: 49-62).
