Validation Data Gallery

Filter:
  • Western Blot (WB) analysis of various lysates using CD81 Recombinant antibody (84644-1-RR)

    WB analysis using 84644-1-RR (same clone as 84644-1-PBS)

    Various lysates were subjected to SDS PAGE followed by western blot with 84644-1-RR (CD81 antibody) at dilution of 1:10000 incubated at room temperature for 1.5 hours. This data was developed using the same antibody clone with 84644-1-PBS in a different storage buffer formulation.

Background Information

CD81 (also known as TAPA1 or 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 an essential receptor for HCV (hepatitis C virus) (PMID: 21428934).
