SDS-PAGE and Western blot analysis of recombinant M. pneumoniae P1 proteins fragments. (A) Coomassie blue stained SDS-PAGE analysis of rP1-I, rP1-II, rP1-III and rP1-IV in E. coli extract. The fragments were expressed in pET28b vector and protein production was induced with IPTG in E. coli. (B) Western blot analysis of induced and uninduced P1 protein fragments rP1-I, rP1-II, rP1-IV (i) and rP1-III (ii), showing reactivity with anti-6X His antibody. (C) Coomassie blue stained SDS-PAGE analysis of Ni2+-NTA purified P1 protein fragments; rP1-I, rP1-II, rP1-III and rP1-IV. (D) Western blot analysis of purified P1 protein fragments rP1-I, rP1-II, rP1-III and rP1-IV showing reactivity with anti-6X His antibody. Lane Marker: Molecular mass marker (kDa); Arrows indicate position of expressed protein.
