Figure 2From: Characterization of the expression of Salmonella Type III secretion system factor PrgI, SipA, SipB, SopE2, SpaO, and SptP in cultures and in miceWestern analyses of the synthesis (B) and secretion (A) of the tagged proteins from bacterial strains T-prgI (13 KD)(lane 1), T-spoE2 (29 KD) (lane 2), T-spaO (36 KD) (lane 3), T-sptP (62 KD) (lane 4), T-sipB (65 KD) (lane 5), and T-sipA (76 KD) (lane 6). The expression of bacterial DnaK was used as the internal control (C). Protein samples were separated in SDS-polyacrylamide gels and reacted with antibodies against the FLAG sequence (A-B) and DnaK (C). Each lane was loaded with material from 5 × 107 CFU bacteria. The molecular masses of some of the proteins in the PageRuler protein size markers (Fermentas) are shown and given in kiloDaltons (KD).Back to article page
