CD81 (TAPA-1) is a cell surface protein which belongs to the tetraspanin superfamily. CD81 is identified as a component of the B lymphocyte receptor (BCR) and as a receptor for the Hepatitis C Virus. 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.

外泌体是由脂质双分子层膜包围的细胞来源的囊泡,直径为50 – 150nm。它们由培养的细胞分泌,并在唾液、血液、尿液、羊水、恶性腹水等体液中观察到。最近的研究表明,外泌体含有各种蛋白质和rna,这表明外泌体在细胞之间的信息传递中起着重要作用。
