Figure 2From: Early activation of quorum sensing in Pseudomonas aeruginosa reveals the architecture of a complex regulonTranscript and protein levels of LasR, RhlR, and RpoS during growth of P. aeruginosa. Top panel, Pseudomonas GeneChip signal levels; bottom panel, immunoblots of clarified lysates with LasR, RhlR, and RpoS specific antibodies. The two low molecular weight bands detected by RpoS antibody in stationary phase lysates represent partially degraded RpoS.Back to article page
