Flow cytometry assay for the binding capacity of the Cy5-labeled sequences TV01, TV05, and TV07 with infected (A) and uninfected (B) A549 cells. The aptamer-candidate concentration in the binding buffer was 250 nmol/L. For infected cells, there is positive correlation between the GFP and TV01 signals (C); for infected cells stained with the DNA library, there is no correlation between the 2 channels (D).
