Immunogen Synthetic peptides [amino acids pos. 450-477 / N-terminal amino acids nos. 4-28] of human cytokeratin 9 (MW 62,129)
Clone Ks9-70-Ks9-216
Isotype Cocktail
Specificity The antibody cocktail is an excellent tool to characterize primary cultures of keratinocytes/skin transplants for application in burn treatment. The antibody reagent represents an excellent marker to study palmoplantar epidermal distribution and differentiation. Specifically reactive in the middle/upper suprabasal layers (stratum spinosum/ granulosum) of the epidermis of palm and sole. CK9 can be detected in primary cultures of palmoplantar keratinocytes when they shift to differentiation-promoting conditions and grow stratified (upper cells). CK9 has not been found in normal, i.e. non-pathogenic, non-ridged epidermis, beside some minor cells surrounding the acrosyringeal ducts. No labelling has been found in epithelial cells of other stratified epithelia such as oesophagus or complex epithelia (e.g. urothelium) or in ductal or simple epithelia. Negative tissues include: muscle, liver and duodenum.
Purification Supernatant
Alternative Name Cytokeratin 9 (KRT9 Antibody Abstract)
Background Keratin 9 is a type I cytokeratin. It is expressed in the terminally differentiated epidermis of palms and soles. Defects in KRT9 are a cause of epidermolytic palmoplantar keratoderma (EPPK). EPPK is an autosomal dominant disease characterized by diffuse thickening of the epidermis on the entire surface of palms and soles sharply bordered with erythematous margins.Synonyms: CK9, Cytokeratin 9, K9, KRT9, Keratin, Keratin-9, Spermatid Perinuclear Ring Manchette Protein K9, Type I cytoskeletal 9
