Linearity of the assay with the newly designed BoNT/A substrate. BoNT/A (0.1–100 LD50/ml) was analysed using the shortened peptide as a substrate. Cleavage products were analysed by LC-MS/MS. Data are presented on a logarithmic scale. Each experiment was repeated 3–4 times. The R2 values of the N- and C-terminal products were 0.99 and 0.98, respectively (P < 0.001 and P = 0.001 for the N and C-terminal fragment, respectively).
