Clone Host Grade Applications
Monoclonal Mouse Supernatant B IH
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. Keratin 9 can be detected in primary cultures of palmoplantar keratinocytes when they shift to differentiation-promoting conditions and grow stratified (upper cells). Keratin 9 has not 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. The antibody cocktail is an excellent new tool to characterize primary cultures of keratinocytes/skin transplants for application in burn treatment.
