This monoclonal antibody CSTEM28 reacts with human desmoglein 2 (DSG2), a type 1 transmembrane protein belonging to the cadherin family. DSG2 is expressed by epithelial cells, cardiomyocytes, endothelial progenitors, and CD34+CD45dim hematopoietic stem and progenitor cells. This adhesion molecule forms cell-cell adhesion complexes called desmosomes that provide tensile strength to tissues that experience mechanical stress. Other than its role in desmosome formation, DSG2 plays a role in barrier integrity, adhesion, migration, cell apoptosis, proliferation, vasculogenic mimicry, and intracellular signaling. DSG2-expressing endothelial progenitor cells are pro-angiogenic, suggesting a role in vasculature formation. On hematopoietic stem and progenitor cells, DSG2 expression is highest on CD38-CD90+ multi-potent cells. DSG2 expression is progressively decreased as a function of differentiation, with DSG2 expression absent on mature lymphocytes. DSG2 also serves as a receptor for adenoviruses and can be shed by mucosal barriers in the intestine. This CSTEM28 antibody has been pre-titrated and tested by flow cytometric analysis of 2102ep cell line. This can be used at 5 µL (0.125 µg) per test. A test is defined as the amount (µg) of antibody that will stain a cell sample in a final volume of 100 µL. Cell number should be determined empirically but can range from 10^5 to 10^8 cells/test. Filtration: 0.2 µm post-manufacturing filtered.Desmosomes are cell-cell junctions between epithelial, myocardial, and certain other cell types. Currently, three desmoglein subfamily members have been identified and all are members of the cadherin cell adhesion molecule superfamily. These desmoglein gene family members are located in a cluster on chromosome 18. This protein has been identified as the autoantigen of the autoimmune skin blistering disease pemphigus vulgaris.
