(a) SGF digestion profiles of the preheated lectin from the Zihua snap bean. In the SDS-PAGE analysis, lane 1 was the molecular weight marker, lane 2 was the pepsine, lane 3 was the native lectin, and lanes 4 to 10 were the SGF digestion pattern of the native lectin at 0 min, 2 min, 5 min, 10 min, 20 min, 30 min, and 60 min. (b) SIF digestion profiles of the preheated lectin from the Zihua snap bean. In the SDS-PAGE analysis, lane 1 was the molecular weight marker, lane 2 was the tryptic, lane 3 was the native lectin, and lanes 4 to 10 were the tryptic digestion pattern of the native lectin at 0 min, 10 min, 20 min, 30 min, 40 min, 60 min, and 90 min.
