Analyses of the specific binding of the NU172 antidote (AD) to the NU172 aptamer in whole human blood and the formation of aptamer/AD complexes using 10% nondenaturing polyacrylamide gel electrophoresis. Blood was first incubated for 2 min with 5 μg NU172. Subsequently, 5 μg NU172 (AD) was added and incubated for 2 min. After isolation of oligonucleotides, samples of 10 μL were analyzed. NS and AD_NS were used as negative controls. Firstly, FAM-labeled ADs were detected using an UV-transilluminator (red colored bands) and then all oligonucleotides were detected using GelRed™ staining (white colored bands). An overlay of FAM and GelRed staining is presented. NS: NU172 (NS), AD: NU172 (AD) FAM, AD_NS: NU172 (AD_NS) FAM.
