SDS-PAGE analysis of total proteins stained with silver nitrate. Lane 1, total protein from E. coli expressing OcCHI; lane CK, total protein from bacteria containing the empty vector alone; Molecular masses of markers are shown to the left in kDa (lane M). The red arrows indicate the recombinant OcCHI protein.
