The mouse monoclonal antibody clone M38 binds to human CD81, a 26 kDa non-glycosylated member of the tetraspanin superfamily (TM4SF). CD81, also known as TAPA-1 (target of an antiproliferative antibody), is expressed on T and B cells, NK cells, monocytes, dendritic cells, thymocytes, endothelial cells, and fibroblasts, and at low levels on granulocytes. CD81 induces B cell adhesion via VLA-4 integrin and has been shown to play a role in early T cell development. CD81 associates with several other cell surface proteins in multimolecular complexes, including CD19, CD21, CD20, CD37, CD53, and CD82 in B cells, and CD4, CD8, and CD82 in T cells.

RECOMMENDED USAGE

Flow cytometry: The suggested use of this reagent is 5 µL per 1 million cells in a staining volume of 100 µL. If whole blood is analyzed, then use 5 µL per 100 µL. It is recommended that users titrate the antibody to obtain the optimal result for their specific application. The content of a vial (0.5 mL) is sufficient for 100 tests.
