Evaluation of Olink Reveal Proximity Extension Assay for High-Throughput Proteomics: A Case Study Using NIST SRM 1950 and Spike-In Protein Standards

ABSTRACT: Plasma proteomics has regained attention in recent years through advancements in mass spectrometry instrumentation and sample preparation, as well as new high-throughput affinity-based technologies. Here, we evaluate the analytical performance of the new Olink Reveal platform, a proximity extension assay based technology quantifying 1,034 proteins across biological pathways. Using spiked-in recombinant Interleukin-10 (IL-10) and vascular endothelial growth factor D (VEGF-D) in the NIST SRM 1950 plasma standard, we assessed the linearity, sensitivity, precision and accuracy of the Olink assay. The results demonstrated strong linear relationships (R² 0.922–0.953) for both IL-10 and VEGF-D across spiked-in concentrations, confirming the robust technical performance of Olink Reveal and underscoring its suitability for relative quantitation in large-scale studies. The resulting data contains no sensitive or personally identifiable information, and is available in public repositories, and therefore suitable for use in benchmarking and software development.
