OLINK® Proximity Extension Assay (PEA) - technology

OLINK® PEA technology is based on the detection of biomarkers generated by binding specific pairs of DNA-tagged antibodies. Matched DNA-tags form hybridization products, and Proximity Extension Assay (PEA) technology forms reporter-templates for multiplexed PCR amplification enabling high-throughput detection of the DNA-reporter-sequences by qPCR or NGS. Due to PCR amplification, this technology allows parallel quantification of many markers over a wide range of several orders of magnitudes, although when biomarkers are present at very different levels in the original specimen. Thus relative quantification of panels of 92, 384 or a total of 3072 biomarkers can be performed from minute amounts of sample volume in a very efficient manner.

Human EDTA, acid citrate dextrose, and sodium heparin plasma and serum are the recommended sample types. Variations observed between responses in heparin, citrate plasma and serum, as compared to EDTA plasma, were generally small and all assays should therefore function without limitation in these sample types. For other sample types, please inquire.

Olink Flex is a flexible, made-to-order biomarker assay that can measure up to 21 human proteins across 40 samples simultaneously. Select and combine targets from a broad mix-and-match library of ~200 inflammation-related human proteins with 99% combinability. Consumes only 1 µL per sample. Results are reported in absolute quantification (pg/mL) and relative quantification (NPX).

Build the Olink Flex assay from scratch using a panel builder or select from curated template panels for cytokine storm, immuno-oncology, or interferon stimulation. Once the order is placed, analysis will be completed within 10 weeks. The minimum order is one assay for up to 21 proteins and 40 samples. Learn more 

Olink Focus is a custom-made assay that provides an ideal solution for protein biomarker validation and beyond. Select and combine up to 21 proteins from the entire protein library of ~3000 human proteins. 144 or 160 samples can be analyzed simultaneously in one assay. Results are reported in absolute quantification (pg/mL) or relative quantification (NPX), and the validation level is customized based on your research needs.

The minimum order is a panel that enables the analysis of up to 21 proteins for 1000 samples. Olink experts will help you design your Olink Focus panel. Once the order is placed, the panel will be developed in less than 6 months. Learn more

SAMPLE TYPE – please inquire.

Sample type
Human EDTA plasma and serum are the recommended sample types. Human citrate plasma and heparin plasma are also accepted. For other sample types e.g. cerebrospinal fluid (CSF), tissue or cell lysates please we recommend Olink Target 96 panels. Please note that protein expression levels are expected to vary in different sample types and certain assays may be affected by interfering substances such as hemolysate. For other sample types, please inquire.

The Olink® Explore HT panel is a high throughput biomarker discovery panel which targets more than 5.400 proteins (inflammatory proteins, tissue-enriched proteins, blood secreted proteins, drug target proteins, exploratory proteins). All protein assays are highly validated and with only 2 µl sample (plasma, serum) input the assay has a specificity of 99,5%. Multiples of 172 samples can be analyzed in parallel. 


With the Olink® Target 48 Mouse Cytokine panel it is possible to monitor longitudinal studies from murine immune response from only 1 µl of mouse sample. This reduces the variability of the study tremendously as the required animal use is minimized. 43 targets (relevant for Inflammation, Immune Response and Immuno-oncology) are measured in parallel and the data will be provided in pg/ml (absolute quantification). Due to the layout of the qPCR Dynamic arrays, 40 samples per analysis run (or multiples thereof) are recommended. 



Sample sending and (pre-)processing

Usually diverse sample types as indicated in the specific sections can be processed without any specific requirements. In certain cases and upon request AIT can offer pre-processing like protein concentration measurements for standardization, sample concentration or dilution and aliquoting samples for specific project settings. These requirements should be defined and considered in advance.

Sample sending: sample-volume 30µl in 96 well plate (v-bottom – skirted) / tightly closed / sealed with aluminium foil suitable for -80°C, please spin down before freezing and send on dry ice.

SAMPLE LAYOUT and positions in the plate has to be defined according to the experiment descriptor layout and provided via email according to the attached file “OrderSheet.xlsx”. Provide the reference number of the offer in the respective field.
