(A) SDS-PAGE of recombinant ehrlichial GST fusion proteins expressed in E. coli BL21 cells. Lane 1, E. canis P140; lane 2, E. chaffeensis P120; lane 3, E. chaffeensis P120 two-repeat units; lane 4, GST protein (28 kDa). (B and C) Specificity of anti-recombinant E. canis P140 (B) and anti-recombinant E. chaffeensis P120 (C) against recombinant E. canis P140 (lanes 1) and E. chaffeensis P120 (lanes 2) proteins after removal of GST by thrombin protease. Numbers on the left of each panel are molecular masses in kilodaltons.
