Description
The MG38 monoclonal antibody reacts with human CD205, also known as DEC-205, an integral membrane protein homologous to the macrophage mannose receptor. CD205 is an endocytic dendritic receptor that mediates efficient processing and presentation of antigens on MHC class II productions
in vivo. CD205 is highly expressed by dendritic cells (DCs) within the T cell areas of lymphoid tissues, particularly on CD8
+ DCs that are believed to play a role in cross-priming. Expression of CD205 is detected with this antibody at high intensity on
in vitro derived mature human DCs (mDC) and at intermediate intensity on immature human DCs (iDC). All leukocytes from peripheral blood show a degree of staining with this mAb that can be minimized by using very low concentrations of MG38.
Applications Reported
For research use only, not for diagnostic or therapeutic use. This MG38 antibody has been reported for use in flow cytometric analysis.
Applications Tested
This MG38 antibody has been pre-titrated and tested by flow cytometric analysis of
in vitro derived human dendritic cells and peripheral blood leukocytes. This can be used at 20 μl (.06 μg) per 100 μl blood (or per 1 million cells in 100 μl total staining volume).
