Fig. 6: Assessment of VHHs capability of neutralising the cell depolarisation caused by long-chain α-neurotoxins in vitro.

The VHHs were preincubated with different long-chain α-neurotoxins at molar ratios ranging from 1:9 to 9:1 (3:1 for αBgtx) VHH:toxin. The resulting normalised peak current is shown. Toxins were used at concentrations ranging between IC10 and IC90, as indicated by the peak current obtained in the absence of VHH.
