Clone LR was obtained after three cycles of directed evolution of the parental clone 3F and incorporating a V101F mutation into one of the derived variant clones (9004G). This antibody clone recognizes and neutralizes the main toxins from the venoms of the C. noxius and Centruroides suffusus suffusus scorpions (Cn2 and Css2, respectively), with affinities in the picomolar range, and removes any poisoning symptoms. In neutralization tests using fresh whole venom in mice, clone LR was capable of inhibiting nearly all symptoms caused by the C. suffusus suffusus venom.
Figure 1 Competition binding assays of scFvs LR and RU1 with the Cn2 toxin.
These results clearly indicated that the scFvs recognized different sites on the toxin. This is significant because the toxins were neutralized through the binding of the scFvs to non-overlapping sites, which improved their efficiency as an antivenom.

Optimal neutralization of Centruroides noxius venom is understood through a structural complex between two antibody fragments and the Cn2 toxin. Journal of Biological Chemistry, 291(4), 1619-1630.
Figure 2 scFv recognition to Cn2 upon treatment under strong denaturing conditions.
ScFv LR exhibited the best recognition, followed by scFv 6009F, and finally by scFv 9004G.
