    Background

    CD81 (also known as TAPA1or TSPAN28) is a membrane protein of the tetraspanin superfamily, which are characterized by the presence of four conserved transmembrane regions. Many of these members are expressed on leukocytes and have been implicated in signal transduction, cell-cell interactions, and cellular activation and development. CD81 is involved in signal transduction and cell adhesion in the immune system (PMID: 9597125). CD81 has also been identified as en essential receptor for HCV (hepatitis C virus) (PMID: 21428934).

    The antibody preformed as desired. The volume of the sample of antibody was low considering prior publications suggested that it be used at 1:250 and I had several blots. It would be good if you offered this item in a larger volume taking into consideration the amount of antibody needed to use in Western Blot.
