Upper panel: Immunoblot analysis of PilY1 in P. aeruginosa cell lysates. From left to right: PilY1-immunoreactive signals from planktonic cells of P. aeruginosa PAO1 (126.6 kDa), lane 1; TBCF10839 (126.3 kDa), lane 2; TBCF10839 pilY1::Tn5 mutant 25C8, lane 3; TBCF10839 pilY1::Tn5 mutant 10CB5, lane 4; TBCF10839 pilY1::Tn5 mutant 25C8 complemented with pME6010::TBpilY1, lane 5; and TBCF10839 pilW::Tn5 mutant 14D1, lane 6; grown until late exponential phase. Equivalent amount from cell lysates were subjected to 6% SDS-PAGE followed by immunodetection with rabbit polyclonal anti-PilY1 antibody (Eurogentec). The asterisk indicates the immunoreactive band of a truncated PilY1 protein in mutant 10CB5. Lower panel: Sensitivity of the rabbit polyclonal anti-PilY1 antibody against the PilY1-specific oligopeptide used for immunization.
