Purification of recombination GhABP19 protein. (A) SDS-PAGE gel electrophoresis for prokaryotic expression of GhABP19. Expressed proteins are indicated in arrows. Lane M, protein molecular weight markers. Lanes 1, 2, 3, and 4, crude extract without IPTG induction, and cultured at 37°C with oscillation for 2, 3, 4, and 5 h, respectively; lanes 5, 6, 7, 8, crude extract with 0.1 mM IPTG induction, and cultured at 37°C with oscillation for 2, 3, 4, and 5 h, respectively. (B) SDS-PAGE of purified recombination GhABP19. Lane M, protein molecular weight markers. Lane 1–5, purifier protein with different elution times.
