Extended Data Fig. 3: Concentration-dependent fluorescence restoration of selected aptamer beacons (Cy3 and BHQ1) in response to gradient concentration of IL-2.
From: Systematic functional screening of switchable aptamer beacon probes
a, The target protein bound to the aptamer beacon, and the fluorescence of the aptamer beacon was restored. b, The fluorescence of AB-I2 was related to the change in the concentration of the target protein. c, The fluorescence of AB-I5 was related to the change in the concentration of the target protein. d, The fluorescence of AB-I5 was related to the change in the concentration of the target protein.
