Background Information
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).

Reviews
What customers say
The single review (3/5) reports that the antibody failed to detect the target protein at the expected molecular weight in HEK293T cell lysates by western blot at a 1:500 dilution. The reviewer noted that WB is not a listed application for this clone and rated it poorly for that use, while acknowledging it may perform as intended for its advertised application in flow cytometry.
The reviews below have been submitted by verified Proteintech customers who received an incentive for providing their feedback.
Christine (Verified Customer) (10-02-2024) | I tried this antibody for western blotting (because this clone has been shown to work in WB in publications) but unfortunately it did not detect any protein at the right size in lysates from HEK293T cells (at 1:500). It is not advertised for use in western blotting and indeed it did not work for me. So I did rate it as poor although it might work as intended for flow cytometry.
