Figure 2From: Type III secretion proteins PcrV and PcrG from Pseudomonas aeruginosa form a 1:1 complex through high affinity interactionsPcrV and PcrG co-migrate in gel filtration. (A) PcrV:PcrG peak fraction after proteins were purified individually and mixed in equimolar amounts prior to gel filtration chromatography; (B) PcrV peak fraction; (C) PcrG peak fraction. Positions of Mr markers (kDa) are shown on the left side of the gel.Back to article page
