Genomic and transcriptomic analyses are now tools to discover new biomarkers. However, changes in protein expression are more likely to characterize the pathophysiology of the disease. In the past, clinical diagnosis relied on antibody-based assays, which had limitations. Now, mass spectrometry (MS), a powerful approach to proteomics research, enables in-depth studies of disease proteomic changes, thereby facilitating personalized drug development.
Standardized, high-throughput sample preparation techniques have enabled the field of clinical proteomics to expand rapidly at the scale of clinical cohorts. Further improvements in mass spectrometer sensitivity and speed allow deeper proteomic coverage, particularly without the need for extensive pre-separation. Quantitative levels will also allow clinical proteomics to evolve toward minimal input sample size and single-cell proteomics. Higher data processing capabilities can uncover more biological information that can be useful. These advances are all necessary for MS-based clinical proteomics to realize its full potential for translating research findings into clinical practice.
While most discovery-based clinical proteomics studies still use a data-dependent acquisition (DDA)-based model to identify potential biomarkers or gain biological insights, the field of clinical proteomics is currently shifting toward a new generation of proteomics technology, data-independent acquisition (DIA). DIA has been used in many top research applications by significantly improving the coverage, reproducibility, and accuracy of proteomics analysis with its missile-bombing full-scan data acquisition.
Overview of clinical cancer proteomics research strategies
Since we started to provide DIA technology and 4D Proteomics service, we have accumulated a lot of experience not only in the detection of a large cohort of conventional samples, but also in providing one-stop service of DIA+PRM+machine learning for biomarker studies, tumor-based proteomic typing, and large-scale clinical sample proteomics analysis based on next-generation chromatography (Evosep DIA). Free consultation is welcome.
