Thrombin cleavage reaction progress at 23°C and 0.35 units of enzyme per mg of protein. A: Reaction curve. The arrow indicates addition of an equal amount of thrombin. B: SDS-PAGE 10% T, 3% C; Tris-Tricine buffer system. Different species are indicated as K-P: KSI-peptide fused peptide; K: KSI partner protein; P: Peptide. M: Molecular weight marker; lanes 1–9: samples of the reaction at different times in hours. Lane 1: 0 h; lane 2: 2 h; lane 3: 4 h; lane 4: 8 h; lane 5: 20 h; lane 6: 30 h; lane 7: 48 h; lane 8: 72 h; lane 9: 96 h.
