Analysis of recombinant BsDb expression in Pichia pastoris. (A) SDS-PAGE analysis: culture supernatant from a negative clone induced by 1% methanol for 96 h (lane 1); culture supernatant from the positive transformant grown under identical condition (lane 2); culture supernatant concentrated 5-fold from the positive transformant (lane 3); and protein molecular weight marker (Sangon, Shanghai, China) (Lane M); (B) Western blot analysis: supernatant from a negative clone (lane 1); culture supernatant from a positive transformant (lane 2); and culture supernatant concentrated 5-fold from a positive transformant (lane 3).
