Immunogenomics Facility

Welcome to the Leeds Immunogenomics Facility (IGF) 

UK’s First Certified Core Facility to Run Olink® Mid-Plex Assays

We use Olink® proteomics technology for targeted protein biomarker research, providing new insights into disease, improving disease detection and helping to understand disease biology. Having been early adopters of the Olink® Proteomics platform in-house for our own biomarker research, we have gained extensive experience which we now offer to external academic groups and industry.

Why Olink?
•    Rapid, high-throughput protein analysis
•    Curated panels of protein biomarkers
•    Compatible with a wide range of sample types
•    Exceptional sensitivity and specificity
•    Uses only 1ul of biological sample
•    Strict assay technical validation and quality control procedures

Olink® PEA Technology

Next-Gen Technology for Highly Accurate, Multiplex Protein Analysis

Olink utilises proprietary Proximity Extension Assay (PEA) technology, which combines immunoaffinity with a qPCR readout to measure proteins with exceptional throughput, sensitivity, and specificity.

Paired antibodies conjugated to complementary oligonucleotide sequences come in close proximity only when they both bind to their specific target protein (see Figure 1 below).

The complementary oligonucleotides hybridize, creating a unique double-stranded barcode for the protein and sample, and subsequently extended and amplified via PCR. For Olink® mid-plex assays, the amplicons are measured using qPCR on the Olink® Signature Q100 and are quantitatively proportional to the initial concentration of the target protein.

The cycle threshold (Ct) values generated from qPCR are translated into relative quantification units known as Normalised Protein eXpression (NPX) values using a series of computations, which minimise technical variation and improve interpretability of results. Importantly, the technical performance of the assay is ascertained using a built-in QC system using internal, spiked-in controls.
