Chromatograms of chymotryptic peptides which contain NFK derivatives from a) Trp 84 (m/z 1058.13+) and b) Trp 279 (m/z 632.32+), respectively. The signal intensity is indicated for the total ion current chromatogram. Analyses of samples containing TcAChE plus MB further irradiated for 20 minutes are indicated by dotted lines (without the inhibitors, ED and PR) and solid lines (with the inhibitors).
