What Is Proteomics?
Proteomics is the study of all the expressed proteins in an organism (proteome).
This includes the presence or absence of specific proteins and expression levels over time, driven by external stressors, treatments, and/or disease state progression.
Why Is Studying Proteomics Important?
Protein expression is directly associated with the potential for disease, its manifestation, and reversion to a normal state.
As part of a multiomics approach along with genomics and transcriptomics, proteomics provides a much more impactful evaluation of an organism at a systems level and hence will lead to quicker and more fruitful discoveries, while helping to identify key clinical and treatment outcomes.
New technologies are being developed to increase sensitivity and throughput beyond Mass Spec, and this is where Olink® and their Proximity Extension Assay (PEA) comes in.
What Can You Do?
Go Beyond Mass Spec
When high throughput and low hands-on time are critical, characterize proteins using Olink® methodologies
Identify Proteomes
Apply the power of NGS sequencing to characterize and quantitate the totality of proteins in your sample
Disease Research
Profile biomarkers in various disease states for both research and therapeutics developments
One-Sample Multiomics
Evaluate gene and protein expression content from a single sample

Olink® Proteomics Tools
Olink® Reveal 
Olink® Reveal offers discovery-level proteomics at an affordable price. The panel targets over 1,000 proteins for a broad view of the proteome and 96% coverage of all immune pathways. The panel includes:
- 537 inflammation or immune response proteins
- Over 850 disease-associated proteins
- Over 700 proteins associated with a quantitative trait locus (pQTL)
Olink® Explore
Actionable, high-throughput human protein profiles specific to cardiometabolic, inflammatory, neurological, and oncological disease states.
- Inflammation / Inflammation II
- Cardiometabolic / Cardiometabolic II
- Neurology / Neurology II
- Oncology / Oncology II
We offer full-scale screening of Olink's Explore 3072 library of validated protein assays. Olink Explore consists of eight individual biologically focused protein panels. Your samples can be assessed by individual panel, four panels, or all eight panels.
Olink® Target 96 & Target 48
The Olink® Target 96 protein biomarker panel assays screen 92 different proteins focused specific disease areas and other important biological processes.
Use Olink® Target panels to improve disease detection, enabling faster, better-informed decisions in human protein biomarker research.
Your sample's relative protein expression is determined using PEA to deliver a qPCR readout.
- Cardiometabolic
- Cardiovascular II
- Cardiovascular III
- Cell Regulation
- Development
- Immune Response
- Immuno-Oncology
- Inflammation
- Metabolism
- Mouse Exploratory
- Mouse Cytokine
- Neurology
- Neuro Exploratory
- Oncology II
- Oncology III
- Organ Damage
The Olink® Target 48 Cytokine panel consist of 45 cytokine biomarkers that can be evaluated by relative or absolute quantification. They are ideal for inflammation-related studies.
Olink® Focus 21 Custom Panels
When you need a very specific set of proteins not covered by Olink's existing panels, Olink® Focus 21 allows you to design your own panel.
Using Olink's resources and validated PEA technology, you can create an extremely targeted panel of 21 proteins on a qPCR platform for your disease indication of interest.
* Olink Focus is compatible with human samples.
Olink® Flex Panels
Choose from approximately 200 inflammation related proteins to design your Olink® Flex panel. Choose between 5 and 30 proteins, or you can select one of several pre-made templates, including immuno-oncology, cytokine storm, or interferon (IFN) stimulation. You can analyze your protein quantity via relative quantitation (NPX) or absolute quantitation (pg/mL).
Selection of proteins simple with the Olink® Flex panel builder.
* Olink Flex is compatible with human samples.
Proximity Extension Assay (PEA)
The cornerstone of Olink® platforms is the Proximity Extension Assay (PEA). You can use PEA to determine Normalized Protein Expression (NPX) values with either an NGS or a qPCR readout.
