Cells: Granulocytes, monocytes, thrombocytes, melanoma cells
Structure: Glycoprotein (40-60 kDa)
Note: CD63 is an intracellular lysosomal granulaprotein which is translocated to the cell surface after activation of granulocytes/endothelial cells (activation marker). CD63 is identical to ME491, an antigen expressed by melanoma cells and associated with early stages of tumor progression.
Application: FACS, IHC (P
