Recombinant monoclonal antibody to Capsid protein VP3. Manufactured using AbAb’s Recombinant Platform with variable regions (i.e. specificity) from phage display VHH-12B.
Immunogen: The VHH-12B was generated by immunizing a dromedary with poliovirus type I Sabin strain, preparing cDNA libraries from lymphocytes, and then selecting for tight poliovirus binders by phage display.
Specificity: VHH-12B binds to a site on the top surface of the expanded poliovirion capsid protein VP3. VHH-12B does not bind to the native, unexpanded virus.
Application Notes: ELISA was used to show the reactivity of VHH-12B for poliovirus (Thys et al, 2010). The interaction of VHH-12B with capsid protein VP3 has been captured using cryo electron microscopy (Strauss et al, 2017).
