The isolated aptamer Clon-3 had nanomolar binding affinity, as determined via both homogeneous and PD-L1 immobilized affinity assays. Clon-3 could be used to recognize various cancer cells with distinct PD-L1 expression levels using flow cytometry. The PD-L1 expression levels in normal human tonsils (the gold standard for anti-PD-L1 antibody) and non-small cell lung cancer tissue sections stained using Cy5.5-labeled Clon-3 were also successfully imaged using a confocal microscope. The fluorescence intensities of the tissue sections were i
