Enhance your data by adding SomaScan® Assay services to your mass spectrometry analysis
Analyze thousands of proteins in 55 µL of plasma, and obtain sensitive detection without complex sample preparation
Adding the SomaScan Assay to mass spectrometry allows for deeper molecular insights, rapidly and consistently
Pairing the SomaScan Assay with complementary technologies, such as mass spectrometry, can accelerate target identification and protein expression analysis, as well as help you differentiate causal links or find new uses for already approved therapeutics.
The SomaScan Assay is based on SOMAmer® (Slow Off-Rate Modified Aptamer) Reagents, which are aptamers that are custom-engineered to have enhanced shape complementarity to their targets, as well as slow off rates for longer target binding. A universal polyanionic competitor further enhances specificity to the target protein.
Our high-plex proteomics platform can measure thousands of proteins simultaneously from a small sample (~55 µL) of plasma, serum, CSF, and multiple other complex sample types (human and non-human). This platform also offers excellent reproducibility with median coefficients of variation (CVs) of ~5%.
Published findings show the benefit of using complementary technologies
- In patients with high-grade serous ovarian carcinoma, researchers used the SomaScan Assay and mass spectrometry to discover protein signatures classifying long- or short-term relapse-free survivors (PMID 31588238)
- Researchers used the SomaScan Platform and mass spectrometry to help identify the role of molecular mechanisms in different pathophysiological processes in COVID-19, a complex, heterogeneous condition. These insights may help stratify patients in clinical trials and in the clinic for targeted treatment (PMID 33724185)
- In a study combining the SomaScan Assay with mass spectrometry analysis, research identified aspirin-targeted proteins that are potentially associated with the risk of colorectal cancer (PMID 33318029)

Benefits of the SomaScan Assay
The SomaScan Assay utilizes small sample volumes and delivers high-quality, actionable data to accelerate your research.
Sensitive detection
(fM)
The SomaScan Assay can measure proteins with low limits of detection (10-log range with fM sensitivity).
Reproducible
(~5% median CV)
Obtain consistent and reproducible inter- and intra- assay results for data analysis and comparison.
High throughput
Enable 11,000 total protein measurements per sample, and conduct high-throughput analysis of >1,000 samples per day.

SomaScan 11K Assay v5.0
The SomaScan Platform is a powerful tool with applications in scientific research and health and wellness. This technical note provides background on the platform itself, as well as performance metrics for the SomaScan 11K Assay v5.0.
SomaScan 7K Assay v4.1
The SomaScan Platform measures native proteins in complex matrices by transforming available binding sites on individual proteins into a corresponding SOMAmer Reagent concentration, which is then quantified by hybridization to microarrays.
Pre-Analytical Variation
Controlling pre-analytical variation is important to avoid misleading analyses that can impact data and cause setbacks in research efforts – costing time, money, and loss of precious samples.
Elements of Specificity
Each SOMAmer Reagent is characterized by two elements of specificity: strong affinity for its target protein and a slow dissociation rate. These two specificity attributes derive from the unique chemical composition of each reagent.
