From
Recombinant Antibody
Specificity
This antibody is specific for the large extracellular loop of human CD81.
Alternative Names
CD81 antigen; 26 kDa cell surface protein TAPA-1; Target of the antiproliferative antibody 1; Tetraspanin-28 (Tspan-28)
UniProt
P60033
Immunogen
The original antibody was generated by immunization of Balb/c and Naval Medical Research Institute (NMRI) mice with CD81 extracellular loop 2 (ECL2) protein.
Application Notes
The scFv version of this antibody is based on an anti-CD81 clone whose binding specificity was determined via FACS that was successfully used in an inhibition assay against HCV (Ji et al., 2015; PMID: 25417967). The exact binding site of this antibody was determined via crystallization (Nelson et al., 2018; PMID: 29778602). The scFv version of this antibody was used successfully in FC (Susa et al., 2020; PMID: 32338599).
