Proximity ligation assay (PLA) achieves extremely low limits of detection but requires the synthesis of antibody-DNA conjugates recognizing multiple target epitopes with appropriate proximity. In this work, we introduce a more generally applicable method by replacing antibody-DNA conjugates with nanoparticles which create ultradetectable PCR templates by capturing biotinylated oligonucleotides and catalyzing ligation. A competitive PCR readout was used to make the assay quantitative. We have dem ...[more]
