Why Quantitative Proteome Profiling Matters
Quantitative proteome profiling provides functional insight into biological systems by capturing precise protein abundance shifts. This approach empowers researchers to map regulatory mechanisms, prioritize therapeutic targets, and translate molecular findings into actionable strategies for precision medicine and biomarker development.
FAQs on Quantitative Proteomics
1. What platform do you use for MS-based quantitative proteomics?
Our quantitative proteomics workflows are powered by the Bruker timsTOF HT platform, which combines TIMS (Trapped Ion Mobility Spectrometry) with PASEF (Parallel Accumulation Serial Fragmentation) to achieve ultra-high sensitivity, resolution, and throughput. It enables 4D proteome analysis with excellent depth and precision.
2. How do I choose between DIA and DDA for protein quantification?
In general, DIA is preferred for larger cohorts and studies that require higher quantitative completeness and reproducibility across many samples, while DDA is often used for discovery-oriented profiling and exploratory projects. If you share your sample type, sample number, and study goal, we can recommend the most suitable quantitative workflow.

3. Do you offer TMT or iTRAQ labeled proteomics?
Currently, we do not offer TMT-labeled or iTRAQ-labeled proteomics. Instead, we specialize in label-free quantitative proteomics, which avoids issues like ratio compression, sample mixing artifacts, and labeling cost. Label-free methods are more flexible for handling large sample sizes and diverse sample types without requiring chemical labeling, while still delivering high-quality quantitative results using advanced mass spectrometry and statistical normalization.
4. Do your quantitative proteomics services accept IP-enriched samples or gel-based samples?
Yes. Quantitative proteomics can be performed on IP-enriched eluates as well as gel bands, gel spots, and gel slices. To maximize compatibility and recovery, workflows support on-bead digestion for magnetic bead and in-gel digestion for gel-separated proteins, enabling reliable LC–MS/MS-based proteome profiling from non-standard sample formats.
5. How do you ensure data quality and reproducibility in proteomics analysis?
We implement comprehensive quality control (QC) measures at every stage of the workflow. This includes internal standards such as iRT peptides, reference samples like HeLa cell lysate, and mixed peptide/protein QC pools. These controls help monitor system performance, retention time alignment, and quantification consistency to ensure reliable, reproducible results across batches and projects.
6. How should proteomics samples be prepared, stored, and shipped for quantitative LC–MS/MS analysis?
For best quantitative proteomics performance, samples should be collected using clean, protein-compatible reagents and processed quickly to minimize degradation. Snap-freeze tissues or cell pellets whenever possible and store at −80°C, avoiding repeated freeze–thaw cycles. For biofluids (plasma/serum), clarify by centrifugation, aliquot, and freeze promptly. Avoid detergents and additives that interfere with LC–MS/MS (e.g., SDS, high salt, excessive glycerol, and nucleic acids); if lysis buffers are used, choose MS-compatible formulations or discuss buffer exchange/cleanup options in advance. Ship samples on dry ice with sealed, clearly labeled tubes to maintain sample integrity.
7. What is the typical turnaround time?
Turnaround time varies depending on the project scope, but standard proteomics services typically require 4–6 weeks from sample receipt to data delivery. Express options may be available upon request.
Key Applications of Quantitative Proteomics Analysis
Biomedical and Clinical Research
Quantitative proteomics enables unbiased protein expression profiling in cancer, inflammation, neurodegeneration, and metabolic disease, supporting biomarker discovery, patient stratification, and mechanism-driven translational studies.
Animal Biology and Translational Models
Proteome profiling in animal tissues and cells captures systemic protein regulation driven by genetics, diet, infection, or pharmacological perturbation, enabling cross-tissue comparisons and pathway-level interpretation.
Plant Biology and Crop Science
Quantitative proteome analysis reveals protein expression changes underlying development, stress adaptation, and hormone responses, helping identify pathways associated with yield, quality, and resilience to environmental challenges.
Microbiology and Host–Microbe Studies
Proteomics supports discovery of regulated proteins involved in microbial growth, metabolism, and virulence, and helps interpret host–microbe interactions by linking protein changes to functional pathways and networks.
