Desmoglein 1 is a member of the desmosomal cadherin family that comprise the desmogleins and desmocollins. Desmosomes are cell-cell junctions in most epithelial cells and serve to link the intermediate filament cytoskeletons of adjacent cells. Within the desmosome the extracellular domain of desmoglein is essential for calcium dependent heterophilic binding to the desmocollins, whereas the intracellular domain is essential for binding to the desmosomal plaque protein, plakoglobin. Desmoglein 1 is synthesized exclusively in the suprabasal layers. Intact and functionally active desmoglein 1 is essential to epidermal integrity. The monoclonal antibody 27B2 reacts with the 165 kDa desmoglein 1 protein. Furthermore it is not cross reactive with desmoglein 2 or desmoglein 3.
Flow cytometry, Frozen sections, Immuno fluorescence, Immuno precipitation, Western blot
For immuno fluorescence and Western blotting dilutions to be used depend on detection system applied. It is recommended that users test the reagent and determine their own optimal dilutions. The typical starting working dilution is 1:10.
