paper</span>Ensuring reproducibility in proteomics: Why coefficient of variation is a critical metric </h3> <p>The SomaScan® Assay from SomaLogic is the only proteomic technology capable of measuring thousands of proteins while achieving a high throughput with high reproducibility. The platform is powered by chemically modified DNA aptamers called SOMAmer® reagents. SOMAmer reagents consist of short single-stranded DNA sequences that incorporate hydrophobic modifications, greatly expanding the physiochemical diversity of the large randomized nucleic acid libraries from which the SOMAmer reagents are selected. The performance metrics for all SOMAmer reagents in human serum and plasma are provided via the SomaScan Assay online menu tool at menu.somalogic.com. Although SomaLogic’s core features (high specificity, sensitivity, and reproducibility) are the main reasons the SomaScan Platform is utilized from biomarker discovery to clinical diagnosis, the power of its low coefficients of variation (CVs) is underappreciated. The SomaScan Assay has maintained a median CV of ~5%, which results in the ability to detect smaller biological changes with higher study power compared to other proteomic technologies. The following discussion captures the vast benefits of low CVs, as well as the specific value of the unrivaled SomaScan Platform CVs.</p> </div> <p class="a-center"><a href="https://somalogic.com/white-paper/ensuring-reproducibility-in-proteomics-why-coefficient-of-variation-is-a-critical-metric/" class="btn blue-border">Learn more</a></p> </div> </div><div class="card white-bg resource-card" style="background-image: url(https://somalogic.com/wp-content/uploads/2022/07/iStock-1214057464-scaled-2-768x256.jpg);" title="Graphic of different size circles with lines connecting them"> <div> <div class="content"> <h3><span class="up">White paper</span>The missing link between genes and disease: Discovery of protein quantitative trait loci using high-plex protein profiling</h3> <p>The ability to sequence the human genome has enabled researchers to identify genetic variants associated with disease risk, but identifying causal genes or mechanisms has proven to be much more difficult.

To accelerate an effective response, we have to move beyond the initial diagnosis to prognosis: Who is most susceptible to developing serious, life-threatening symptoms? Currently, there is no way to tell whether an infected individual (or an individual who may become infected) will be asymptomatic or require hospitalization. This wide variation in disease severity is, at least in part, a reflection of the myriad changes that occur within a person’s body as it fights the virus, which in turn reflect the unique biological makeup of that individual.</p> </div> <p class="a-center"><a href="https://somalogic.com/white-paper/infectious-disease-whitepaper/" class="btn blue-border">Learn more</a></p> </div> </div><div class="card white-bg resource-card" style="background-image: url(https://somalogic.com/wp-content/uploads/2022/07/iStock-126699306410-resize-768x512.jpg);" title="Image of female scientist holding a vile of blood"> <div> <div class="content"> <h3><span class="up">White paper</span>Assessing pre-analytical variation for more accurate proteomic data</h3> <p>Results are only as good as the samples used to generate them. Good sample in, good data out. In fact, analysis of uncontrolled samples can generate misleading data and cause setbacks in research efforts that cost time, money, and possible loss of precious samples. Biological samples are inherently variable and can differ greatly in their stability. For example, DNA is relatively stable and can often withstand harsh storage conditions. Proteins, however, are particularly vulnerable to inconsistent collection methods, storage temperatures, and processing methods. It is thus critically important to minimize pre-analytical variation when preparing samples for protein assays. </p> </div> <p class="a-center"><a href="https://somalogic.com/white-paper/minimizing-pre-analytical-variation-to-preserve-sample-integrity/" class="btn blue-border">Learn more</a></p> </div> </div><div class="card white-bg resource-card" style="background-image: url(https://somalogic.com/wp-content/uploads/2022/07/iStock-1014817786-scaled-1-768x513.jpg);" title="Image of female looking into camera"> <div> <div class="content"> <h3><span class="up">White paper</span>Detection of low-abundance serum proteins associated with Prediabetes for predictive and prognostic purposes</h3> <p>Diabetes mellitus refers to a family of metabolic disorders that are characterized by elevated blood glucose concentrations, or hyperglycemia.

It has been shown that aging activates common transcriptional patterns across most organs and tissues, such as inflammatory, stress response and transcriptional regulation pathways1, suggesting the changes are systemic and interrelated. Exposing a young, healthy organism to plasma from old mice, for example, slows down tissues regeneration in a manner that resembles aging2. Conversely, exposure to plasma from young blood is capable of restoring youthful phenotypes 3,4.
