CD63 (also known as LAMP-3, Melanoma-associated antigen ME491, TSPAN30, MLA1 and OMA81H) is a cell surface glycoprotein which belongs to the tetraspanin superfamily. CD63 is known to complex with integrins. CD63 is expressed on activated platelets, monocytes and macrophages, and is weakly expressed on granulocytes, T cells and B cells. Importantly, it is found on the surface of exosomes.
Exosomes are cell-derived vesicles bounded by a lipid bilayer membrane and exhibiting a diameter of 50 to 150 nm. They are secreted from cultured cells and are observed in body fluids such as saliva, blood, urine, amniotic fluid, malignant ascites. Recent studies indicate that exosomes contain various proteins and RNAs, suggesting a role in information transfer between cells.
This monoclonal antibody can be used to immunoprecipitate exosomes from serum and culture supernatants.
