Figure 4.
Detection of elastase and protease LasA in the P. aeruginosa cell-free secretome. Cell-free supernatants obtained from 24 h cultures of PAO1 and CF isolates 5, 6 and 7 grown under normoxia (+) and anoxia (−) were subject to protein precipitation, SDS-PAGE electrophoresis and MS analysis. Data represents N = 1 from five pooled samples. The abundance of elastase and protease LasA is expressed as fold-change compared to normoxia.
