Under circumstances of limited sample availability and the challenge of detecting low-abundance proteins, researchers face a critical question: how can reliable and reproducible protein expression data be obtained? Olink Proteomics provides a solution. With high-throughput and high-sensitivity detection capabilities, it accurately presents complex molecular-level changes, helping researchers comprehensively analyze the dynamic characteristics of biological systems.
In recent years, proteomics has gained increasing prominence as a critical discipline for elucidating disease mechanisms, identifying potential biomarkers. Nevertheless, the detection of low-abundance proteins, the limitations imposed by small sample volumes, and the challenge of ensuring cross-batch data reproducibility remain persistent technical obstacles in both academic and industrial settings. Addressing these bottlenecks, MtoZ Biolabs has integrated the Olink Proteomics platform into its established multi-omics testing infrastructure. The platform couples high-throughput analytical capability with high-sensitivity measurement techniques, enabling accurate quantification of a broad spectrum of proteins from minimal sample inputs.
Overview of Olink Proteomics
1. Technical Principle
Olink Proteomics is founded on the Proximity Extension Assay (PEA) technology. The core principle involves the use of two oligonucleotide-labeled antibodies, each recognizing a distinct epitope of the target protein. When these antibodies bind in close proximity on the protein surface, their conjugated oligonucleotides are brought together, enabling a DNA polymerization event that generates a unique DNA sequence identifier. Signal quantification is subsequently performed using real-time quantitative PCR (qPCR) or high-throughput sequencing, allowing for highly sensitive detection of target proteins from extremely low sample concentrations.
This approach offers significant advantages, including the minimization of non-specific signal interference, enhanced accuracy and sensitivity, and a streamlined experimental workflow. Compared with mass spectrometry-based proteomic approaches, PEA is advantageous for detecting low-abundance proteins and enables broader quantification while requiring only minimal sample input.
2. Analytical Advantages
(1) High throughput: A single assay can simultaneously quantify hundreds to thousands of proteins, thereby markedly improving experimental efficiency.
(2) Low sample requirement: Large-scale profiling can be achieved using minimal sample volumes, making it particularly suitable for studies involving rare or limited-quantity samples.
(3) High sensitivity and specificity: Enables precise detection of low-abundance proteins and reliable discrimination among homologous proteins.
(4) High reproducibility: Implementation on a unified platform with standardized protocols ensures consistent results across different batches and experimental projects.
3. Complementarity with Other Proteomic Approaches
Olink Proteomics is not intended to replace mass spectrometry or other proteomic platforms; rather, it complements them. Mass spectrometry excels in broad, unbiased exploratory analyses, whereas Olink is optimized for sensitive, targeted quantification. Together, they create a comprehensive evidence chain from discovery to validation.
Applications of Olink Precision Proteomics
1. Basic Research
Enables in-depth profiling of protein expression in cells and tissues, supporting analysis of interaction networks and signaling pathway dynamics. This is essential for understanding biological processes, elucidating disease pathogenesis, and identifying regulatory factors.
2. Biomarker Research
Facilitates rapid screening of potential biomarkers with high throughput and sensitivity, followed by iterative validation for stability and specificity. This approach improves both the efficiency and reliability of biomarker discovery.
3. Precision Medicine
Provides robust data for disease subtyping, risk stratification, and therapeutic response evaluation, supporting individualized clinical interventions.
4. Drug Development
Generates high-quality protein datasets for target identification, mechanism studies, efficacy assessment, and safety monitoring. By profiling protein expression dynamics under drug treatment, researchers can more accurately evaluate therapeutic potential and risk.
