(A) Changes in the percentage reduction (from the absorption) in reduced Alamar blue at 570 nm in the presence of 4T1-Luc2 untreated cells or incubated with anti-VCAM-1 ssDNA full length (11R6), truncated aptamer (A11R6), or anti-IL4Rα RNA aptamers (Cl42RNA) for 3.5, 5.5 and 24 h. (B) Change in the fluorescence intensities of reduced alamar blue at 590 nm in the presence of 4T1-Luc2 cells untreated or incubated with anti-VCAM-1 ssDNA full length (11R6), truncated aptamer (A11R6), or anti-IL4Rα RNA aptamers (Cl42RNA) for 3.5, 5.5 and 24 h.
