Plasma Proteomics and Targeted Quantitative Biology

prm-PASEF-based Biomarker Discovery in serum from Colon Cancer Patients

Patient serum is a preferred biofluid for diagnostic purposes as it is readily available. The biomarker detection in serum is usually hindered by the enormous dynamic range of protein abundance, making the reliable measurement of lower abundant proteins challenging. Targeted proteomic analysis of selected proteins offers an alternative to dig deeper and detect low abundant protein in this complex matrix. The development of PRM-PASEF combines the advantages of PRM with the additional selectivity of ion-mobility. Using an extensive collection of isotope-labeled reference peptides, we systematically screened patient serum for biomarkers with a high dynamic range in a very short time using fast liquid chromatography.

Toward Comprehensive Plasma Proteomics by Orthogonal Protease Digestion

Rapid and consistent protein identification across large clinical cohorts is an important goal for clinical proteomics. Here we apply a simple and accessible tip-based workflow for the generation of DIA spectral libraries to provide a comprehensive overview on the plasma proteome in individuals with and without active tuberculosis (TB). To boost protein coverage, we utilized non-conventional proteases together with the gold standard trypsin, identifying more than 30,000 peptides mapping to 3,309 proteins. Application of this library to quantify plasma proteome differences in TB infection recovered more than 400 proteins in 50 minutes of MS-acquisition, including the direct detection of diagnostic Mycobacterium tuberculosis (Mtb) proteins.




Single Cell Proteomics and PaSER Real-Time Search
Friday, November 19, 06:45 - 07:45 am CET (05:45 - 06:45 UTC)

Research Single Cell Proteome (SCP) using Glass-Oil-Air-Droplet (GOAD) nano chip device and its application on embryo development

Deep single-cell proteome has great biological significance for understanding cellular heterogeneity. To overcome the barriers along the processes of shotgun SCP, we firstly developed a nanoliterscaled glass-oil-air-droplet (GOAD) chip using miniaturized stationary droplet microreaction and manipulation techniques for multi-step sample pretreatment. We identified more than 1300 protein groups from a 200pg standard cell digest using timsTOF mass spectrometer in parallel-accumulation-serial-fragmentation (PASEF) scanning mode. We further demonstrate the application of GOAD chip device for the first time SCP analysis on embryo development. This method has great potential for achieving ultrasensitive proteomic analysis on single-cell level.

PaSER and CCS-aware 4D Informatics

PaSER is a real time GPU-based search engine designed to take advantage of the massive parallelization possible on GPUs to enable real time search.  Real-time database search means that bottom-up shotgun proteomics data can be processed as quickly as it is acquired by the mass spectrometer.  This results in “Run and Done”, meaning that when your sample run is done the database search results are ready and can be used for making real time decisions about the next steps in your sample queue.  PaSER will also implement the use of CCS values obtained with 4D-Proteomics methods for improving the FDR in database searches and in particular to improving de novo peptide identification. Additional late breaking developments in PaSER portfolio will be discussed.
