Fig. 5.

MALDI-TOF MS spectra of Fallopia japonica-leaf acid-soluble proteins: extracted from fresh leaf material (a–c), extracted from crushed-leaf fluids dried onto filter paper (d–f), extracted from crushed-leaf fluids dried onto filter paper and then soaked for 10 min in 70% (v/v) ethanol before re-drying (g–i), and extracted from crushed-leaf fluids dried onto filter paper and then autoclaved before re-drying (j–l). Spectra are shown baseline-subtracted, smoothed, y-axis-autoscaled, and covering the mass range 2–20 kDa (with x-axis scale increments of 2 kDa)
