Fig. (1). Electrophoretical profile of outer membrane proteins from tEPEC and aEPEC. Line 1: OMP extract from tEPEC grown in DMEM, Line 2: OMP extract from aEPEC grown in D-MEM, Line 3: OMP extract from tEPEC grown in LB. Line 4: OMP extract from aEPEC grown in LB. MM: molecular marker - low molecular weight (AmershanBiotech), in kDa.
