Figure 4.
Correlation between the frequency of blocking events and the concentration of synthetic peptide Sb2(76-93)s. Peptide was applied to the cis chamber at +120 mV. The linear fitting of the log–log plot by the equation log(f) = a·log([Sb2(76-93)s]) + b (a = 0.55, b = 0.22, R2 = 0.98) represents a calibration curve for the BoNT-B nanopore detector.
