We demonstrate the first application of a nuclease resistant aptamer, the so-called Spiegelmer, in a sandwich-type affinity assay by quantitative assessment of cardiac Troponin I (cTnI) in blood serum samples. To this end, we used a bead-based homogenous proximity assay (AlphaLISA) in which luminescence is generated by the Spiegelmer and antibody-modified donor and acceptor beads brought into proximity by their binding to cTnI.
