Proximity extension assay

The animation explains how our innovative dual recognition, DNA-coupled methodology provides exceptional readout specificity, enabling high . For each biomarker, a matched pair of antibodies linked to unique oligonucleotides (proximity probes) binds to the respective protein target. Assays without the need for washing steps while still unaffected when analyzing complex biological samples are difficult to develop. Among proteins in the Proseek Multiplex Oncology Ivpanel, were above the limit of detection (LOD) in liquid plasma .

The combination of these technologies, leading first to the development of immuno-PCR (iPCR) an more recently proximity ligation (PLA) and extension ( PEA) assays , couples the detection specificity of the antibody with the amplification power of PCR or RCA.

This arsenal is beginning to provide researchers with a .
