Method development for simplified High-Throughput Plasma Proteomics


ABSTRACT: We developed a simplified proteomics sample preparation method that increased the sensitivity and reproducibility of large-scale plasma samples. Peptide loss was reduced while sensitivity was increased by eliminating the peptide clean-up step and using disposable trap column tips. The simplified High-Throughput Plasma Proteomics (sHTPP) method was evaluated using a systemic approach. We identified and quantified more than 500 proteins in non-depleted plasma samples without missing values as the DIA approach improved in terms of identification and quantification. Furthermore, 96-well plate sample handling with a multi-channel pipet allows for high-throughput sample analysis. In a large-scale clinical trial with 300 plasma samples, we used the method to demonstrate robust and accurate quantifications.

Mass spectrometry-based clinical proteomics requires high throughput, reproducibility, robustness, and comprehensive coverage to serve the needs of clinical diagnosis, prognosis, and personalized medicine. Oftentimes these requirements are contradictory to each other. We report the development of a streamlined High-Throughput Plasma Proteomics (sHTPP) platform for untargeted profiling of the blood plasma proteome, which includes 96-well plates and simplified procedures for sample preparation, di  ...[more]
