The binding capacity of candidate aptamers to S. aureus by flow cytometry analysis. The FITC-labeled individual aptamer was incubated with 10⁷ target bacteria (S. aureus 8325-4) or non-target bacteria (Streptococcus A5005) at 37°C for 45 min. The selected aptamers with higher ranked specificity and sensitivity were depicted with solid lines, and the GP45 naive library control and candidates with lower ranked specificity and sensitivity were depicted with dot lines. Representative results of three separate experiments.
