Unlock the future with only a finger prickÂ
Proteomics methodologies are gaining traction, leading to the discovery of numerous disease-related biomarkers and potential drug targets. By analyzing the diverse and complex protein content in blood plasma, researchers can identify biomarkers crucial for early diagnosis, prognosis, and personalized treatment strategies.
Requiring only a finger prick of blood, plasma proteome profiling could easily be performed throughout the patient’s lifetime, from birth to the later years of life. Certainly, for a widespread adoption of proteomics in the clinic, the entire workflow from sample preparation through LC-MS and data analysis needs to become significantly faster and more sensitive to enable the required throughput.
This approach offers a shift from conventional one-size-fits-all healthcare towards tailored interventions for individual patients.Â

Mapping health and genetics through plasma proteomics
A simple blood test can reveal a wealth of information about our health. A new study published in Nature Genetics demonstrates the power of plasma proteomics as a liquid biopsy.
Researchers from the Max Planck Institute in Martinsried, the University of Copenhagen, and Novo Nordisk analyzed 2,147 samples from children and adolescents, identifying 1,216 proteins linked to genetics, age, sex, and BMI.
This high-throughput approach, powered by Evosep technology, highlights the potential of plasma proteomics for understanding health and disease across all stages of life.
Elevate efficiency with automation
Simplification and standardization of workflows is preferred for applications such as plasma proteomics.
The Evosep One not only facilitates robust and reproducible high-throughput analysis of large-scale sample cohorts but is also complemented by automated Evotip loading. The Evotip speeds up your sample loading, reduces carry-over and is a significant contribution to why proteomics has become so easy and routine.
This means that you can reduce manual labor, enhance efficiency, sensitivity, and cost-effectiveness, while ensuring consistent and reliable results across diverse sample cohorts. All ideal when doing large scale plasme proteomics.

SIMPLIFIED WORKFLOWS WITH HIGH REPRODUCIBILITY
One of the key advantages of plasma proteomics is its ability to detect proteins and post-translational modifications with high sensitivity and specificity.
However, plasma proteomics comes with its set of challenges. Plasma is a complex mixture of proteins, including low abundant proteins and those masked by more abundant ones. Additionally, some proteins may have modified sequences, further complicating their detection. Overcoming these challenges requires robust analytical techniques and optimized workflows to ensure reliable and reproducible results.
Mass spectrometry based proteomics enables researchers to quantify proteins and characterize protein patterns, offering a more comprehensive understanding of disease mechanisms and patient-specific responses to treatment. With the right technology researchers can overcome challenges and accelerate the translation of plasma proteomics research into new applications, ultimately improving patient outcomes.

scaling up Lung Cancer Screening with a multi system setup
In this study blood from over 2,500 patients were screened using multi-omics approaches for detection of proteins, metabolites, and transcripts with the aim of generating multiplexed biomarker panel for early lung cancer detection.
Due to high system to system reproducibility combined with our 60SPD standard method they were able to split Analysis across four Evosep One systems for parallel sample processing. This allowed for efficient screening of a large cohort of samples.
This Deep plasma proteome profiling was enabled by automated sample processing, based on the Seer Proteograph assay, coupled to the Evosep One and Bruker timsTOF HT mass spectrometers.
The proteome profiling workflow resulted in the detection of >8,000 protein groups in at least one subject and >5,900 protein groups detected in least 25% of the subjects.

A cost efficient strategy for high-thorughput plasma depletion of >3000 samples
In this study researchers from the Boston Children’s Hospital present a simple, validated, time- and cost-efficient, high-throughput protocol for plasma depletion. Their method was used to process over 3200 plasma samples, proving to be both robust and highly reproducible. By leveraging the Evosep One system, the researchers streamlined and simplified their methodology, achieving notable cost savings.
The Evosep One system contributed to reduced consumable costs by maximizing sample recovery and minimizing sample loss, thereby decreasing the consumption of expensive chromatography materials and reagents. Overall, the study presents a cost-efficient and reliable high-throughput plasma depletion technique, facilitating comprehensive plasma profiling and detecting over 1300 proteins per run.
With a throughput of 60 samples per day, the method underwent extensive validation, processing over 3000 samples without any discernible batch effect, and costing approximately $2.5 per sample (reagents and lab ware)Â for the depletion step.

Fully automated Evotip loading of up to 192 samples in six hours
This study address the challenges of doing high-throughput sample preparation in large cohort plasma studies without compromising sensitivity or reproducibility, even at low sample amounts.
To do so, they developed a Fully automated workflow for integrated sample digestion and Evotip loading. The workflow is based on the Opentrons OT-2 platform and combines PAC digestion using magnetic micro-beads with automated loading of resulting peptides directly on Evotips for reproducible desalting and storage of samples. By integrating digestion and sample loading on Evotips, it minimizes hands-on time, increases throughput, and significantly reduces sample input and required reagents.
Their results showcased that the workflow is reproducible and stable with a proteome depth on par with what would be expected in manual workflows.
