Fig 5. Native PAGE stained with 3 mM L-DOPA (left) showed active bands for extract of Tenebrio molitor (T), Alphitobius diaperinus (A) and Hermetia illucens (H).

Two pooled active fractions from the same insects were subjected to PAGE analysis (T_III, T_IV, A_III, A_IV, H_III and H_IV). Numbering on the left highlights the bands excised and further subjected to proteomic analysis. A similar gel was stained with Coomassie (right).
