Anti-CD81 [CD81K04]

This antibody is specific for a conformational epitope in the extracellular domain of human CD81, a receptor used by hepatitis C virus to infect human hepatocytes.

This antibody has been identified as a potential anti-hepatitis C virus (HCV) agent (Ji et al, 2015). It displays potent and broad-spectrum inhibition of HCV entry in vitro, and has been shown to both prevent HCV infection and limit HCV spread in mice models (Ji et al, 2015) by blocking viral engagement of CD81.The binding specificity of this antibody has been confirmed in FACS analysis (Ji et al, 2015). A Fab fragment of this antibody has been used to determine the crystal structure of CD81K04 binding to the large extracellular loop of CD81 (Bujotzek et al, 2016).
