A Precision proteomics solution for targeted human protein biomarker discovery
Olink’s panels for precision proteomics enable faster, better-informed decisions in human protein biomarker research by providing high-multiplex immunoassays that do not compromise on either data quality or performance. This helps scientists to bring new insights into disease processes, improve disease detection, and contribute to a better understanding of biology. Identifying multiple proteins that form a signature is more powerful and reliable than looking at a single protein. Achieving this requires casting a wide net, with studies that examine many different proteins simultaneously, in large numbers of human samples. Olink enables this today, providing an ever-expanding range of panels for high quality precision biomarker discovery.

Our innovative technology
Olink’s precision proteomics panels are able to achieve such a high level of multiplexing while maintaining exceptional data quality thanks to our proprietary Proximity Extension Assay (PEA) technology. Each biomarker is addressed by a matched pair of antibodies, coupled to unique, partially complementary oligonucleotides, and measured by quantitative real-time PCR. This dual recognition, DNA-coupled method provides exceptional readout specificity, since unlike in many other immunoassay formats, any antibody cross-reactivity that may occur during the multiplexed assay is excluded from the detection process. Go to the PEA technology page to read more about how it works, and see the movie!
PEA technology enables high multiplexing levels without compromising on data quality: the figure compares dCq-values from single assays for Growth Hormone (GH) and Matrix Metalloproteinase (MMP-7) with the equivalent assays performed in a full 96-plex reaction.
Using PEA, our panels can provide accurate quantification below picogram per milliliter levels even in small samples from, for example, needle biopsies or micro dialysis. This minimal sample consumption makes our precision proteomics solution especially suitable for retroactively mining precious biobanked serum samples for new multivariate biomarker signatures. Fully validated in serum & plasma, PEA is also compatible with a wide range of different sample types.
The opportunities are enormous for powerful analysis of multivariate biomarker patterns. Reactions are quantified by real-time PCR using the Fluidigm BioMark™ HD real-time PCR platform. The assay generates as much as 9,216 datapoints per run which can then be analyzed with GeneEx software, equipped with the user-friendly data import wizard.
Together, our panels span a broad dynamic range of protein concentrations. This is optimized within each panel for overall assay performance, and designed to cover expected ranges in normal and pathological samples.
