A nanoLC-MS/MS system using a nonporous reverse phase column for ultrasensitive proteome analysis

ABSTRACT: The design of proteome projects is often restricted by the available amounts of sample, and thus there has been much effort to date to improve the sensitivity of proteome analyses. We have developed a new ultrasensitive nanoLC-MS system for the proteome analysis of microscale samples using a nonporous reverse phase column. Although nonporous particles have low binding capacity due to low functional group density, we found that the use of C30 particles compensated for this disadvantage and nanoLC-MS proteome analyses of microscale samples using a C30-packed column exhibited superior performance compared to porous C18 columns.

Standard Pressure LC-MS/MS Using 1.9um C18 Particles Column at Room Temperature

Project description:Although the benefits of reduction of the size of reversed phase particles are established to provide increased sequencing depth and improved chromatography in LCMS experiments, the wide-scale adoption of optimally sized small particles in reversed-phase columns has been hampered by the necessity for specialized equipment such as ultra-high pressure liquid chromatography or a customized column heating apparatus. Here, we introduce a new strategy to routinely fabricate a 50 cm-long, 1.9 µm particle C18 column and extensively characterize the performance of this column. This column was packed under 100 Bar and routinely utilized on a standard quarternary HPLC at pressures below 300 Bar. Expanding the depth of sequencing of peptides that show a statistically significant quantitative change arising from a biological stimulation is critical. Compared with traditional C18 columns packed with 3 µm particles, the column with the 1.9 µm particles operated with a standard HPLC could detect 330% more peptides with statistically significant changes from differentially stimulated T cells. This improved column fabrication methodology provides an inexpensive improvement for single-run LC-MS/MS analysis to optimize sequencing depth, dynamic range, sensitivity, and reproducibility. This study also highlights the importance of the statistical analysis of quantitative proteomic data instead of a sole focus on peptide spectrum match yields.

Deep single-shot nanoLCMS proteome profiling with 1500 bar UHPLC system, long fully porous columns, and HRAM MS

Project description:This study demonstrates how the latest UHPLC (ultra-high-performance liquid chromatography) technology can be combined with high-resolution accurate-mass (HRAM) mass spectrometry (MS) and long columns packed with fully porous particles to improve bottom-up proteomics analysis with nano-flow liquid chromatography mass-spectrometry (nanoLCMS) methods. The increased back pressures from the UHPLC system enabled the use of 75 µm I.D. x 75 cm columns packed with 2 µm particles at a typical 300 nL/min flow rate as well as elevated and reduced flow rates. The constant pressure pump operation at 1500 bar reduced sample loading and column washing/equilibration stages and overall overhead time that maximizes MS utilization time. The versatility of flow rate optimization to balance the sensitivity, throughput with sample loading amount, and capability of using longer gradients contribute to a greater number of peptide and protein identifications for single-shot bottom-up proteomics experiments. The routine proteome profiling and precise quantification of >7,000 proteins with single-shot nanoLC-MS analysis open possibilities for large-scale discovery studies with deep dive into the protein level alterations.

Open-Tubular Trap Columns: Towards Simple and Robust Liquid Chromatography Separations for Single-Cell Proteomics

Project description:Nanoflow liquid chromatography-mass spectrometry is key to enabling in-depth proteome profiling of trace samples such as single cells, but these separations can lack robustness due to the use of narrow-bore columns that are susceptible to clogging. In the case of single-cell proteomics, offline cleanup steps are generally omitted to avoid losses to additional surfaces, and online solid-phase extraction/trap columns frequently provide the only opportunity to remove salts and insoluble debris before the sample is introduced to the analytical column. Trap columns are traditionally short, packed columns used to load and concentrate analytes at flow rates greater than those employed in analytical columns, and since these first encounter the uncleaned sample mixture, trap columns are also susceptible to clogging. We hypothesized that clogging could be avoided by using large-bore porous layer open tubular trap columns (PLOTrap). The low back pressure ensured that the PLOTraps could also serve as the sample loop, thus allowing sample cleanup and injection with a single 6-port valve. We found that PLOTraps could effectively remove debris to avoid column clogging. We also evaluated multiple stationary phases and PLOTrap diameters to optimize performance in terms of peak widths and sample loading capacities. Optimized PLOTraps were compared to conventional packed trap columns operated in forward and backflush modes, and were found to have similar chromatographic performance of backflushed traps while providing improved debris removal for robust analyses of trace samples.

Highly reproducible improved label-free quantitative analysis of cellular phosphoproteome by optimization of LC-MS/MS gradient and analytical column construction

Project description:Expanding the sequencing depth of the peptides showing a statistically significant quantitative change arising from a biological stimulation is critical. Here we demonstrate that optimization of LC gradient and analytical column construction can reveal over 30,000 unique peptides and 23,000 phosphopeptides at high confidence. The quantitative reproducibility of different analytical workflows was evaluated by comparing the phosphoproteome of CD3/4 stimulated and unstimulated T-cells as a model system. A fritless, 50 cm-long column packed with 1.9 µm particles operated with a standard pressure HPLC significantly improved the sequencing depth 51% and decreased the selected ion chromatogram peak spreading. Most importantly, under the optimal workflow we observed an improvement of 330% in detection of significantly changed phosphopeptides in the stimulated cells compared with the other workflows. The discovery power of the optimized column configuration was illustrated by identification of significantly altered phosphopeptides harboring novel sites from proteins previously established as important in T cell signaling including A-Raf, B-Raf, c-Myc, CARMA1, Fyn, ITK, LAT, NFAT1/2/3, PKCα, PLCγ1/2, RAF1, and SOS1. Taken together, our results revealed a simple column fabrication methodology that provides an inexpensive improvement for single-run LC-MS/MS analysis to optimize peptide sequencing depth, dynamic range, sensitivity, and label free quantitative reproducibility.

Development and performance evaluation of an ultra-low flow nano liquid chromatography-tandem mass spectrometry set-up

Project description:Liquid chromatography-tandem mass spectrometry (LC-MS/MS) is the most commonly used technique for the identification and characterization of proteins. The ionization and transmission efficiency of the electrospray process is a critical factor in LC-MS/MS, ultimately limiting the sensitivity of the approach. Despite the benefits associated with very low flow rates for the ionization efficiency, most nanoLC-MS/MS platforms are operated at relatively high flow rates, aiming for a compromise between sensitivity and practicality. The purpose of this work was to target the latter issue and to develop a robust and user-friendly nanoLC system operable at a flow rate of 20 nL/min, applicable for routine analysis in proteomics laboratories. Peptide separation was performed with an analytical column packed with 2 um porous chromatographic beads, a length of 25 cm and an inner diameter (i.d.) of 25 um. Samples were concentrated and desalted using a trapping column in a vented configuration. The nanoLC system was interfaced to a Q Exactive mass spectrometer using commercially available nanoelectrospray emitters. Practical usability, reproducibility and overall performance of the system were evaluated with a tryptic peptide mixture generated from HeLa cells. Using 100 ng of sample, we identified on average 3,721 protein groups based on 25,699 unique peptides when using linear gradients of 14 hrs. We demonstrate that the number of unique peptides identified with this system increases with decreasing flow rates and in a linear fashion with the chromatographic peak capacity of the separation. Probing the sensitivity of the complete set-up we analyzed only 10 ng of the sample, identifying an average number of 2,042 protein groups based on 11,424 peptides in an 8 hrs. gradient.

Benchmarking of 5.5 cm, 50 cm and 110 cm micropillar array columns as compared to packed bed columns

Project description:A comprehensive proteome map is essential to elucidate molecular pathways and protein functions. Although great improvements in sample preparation, instrumentation and data analysis already yield-ed impressive results, current studies suffer from a limited proteomic depth and dynamic range there-fore lacking low abundant or highly hydrophobic proteins. Here, we combine and benchmark advanced micro pillar array columns (µPAC) operated at nanoflow with Wide Window Acquisition (WWA) and the AI-based CHIMERYS search engine for data analysis to maximize chromatographic separation power, sensitivity and proteome coverage. Our data shows that µPAC columns clearly outperform classical packed bed columns boosting peptide IDs by up to 50% and protein IDs by up to 24%. Using the above-mentioned analysis platform, more than 10,000 proteins could be identified from a single 2 h gradient shotgun analysis for a triple proteome mix of human, yeast and E. coli digests. At high sample loads of 400 ng all three uPAC types yielded comparable number of protein identifications, whereas the 50cm neo column performed best when lower inputs of less than 200 ng were injected. Due to its unique architecture, the 5.5 cm brick column facilitates a highly meandering flow along the brick-shaped micropillars leading to an effective flow path length similar to the 50 cm neo column, while at the same time allowing high flow rates up to 2.5 µL/min. This enables to reduce overhead time by applying high flow rates during sample loading and column equilibration improving sample throughput to ~100 samples per day, while maintaining high protein ID numbers. Particularly for the single cell field, for which throughput is currently one of the most limiting factors, this column could present a valuable asset.

Chitin utilization by marine picocyanobacteria and the evolution of a planktonic lifestyle.

Project description:Marine picocyanobacteria Prochlorococcus and Synechococcus, the most abundant photosynthetic cells in the oceans, are generally thought to have a primarily single-celled and free-living lifestyle. However, while studying the ability of picocyanobacteria to supplement photosynthetic carbon fixation with the use of exogenous organic carbon, we found the widespread occurrence of genes for breaking down chitin, an abundant source of organic carbon that exists primarily as particles. We show that cells that encode a chitin degradation pathway display chitin degradation activity, attach to chitin particles, and show enhanced growth under low light conditions when exposed to chitosan, a partially deacetylated soluble form of chitin. Marine chitin is largely derived from arthropods, which underwent major diversifications 520 to 535 Mya, close to when marine picocyanobacteria are inferred to have appeared in the ocean. Phylogenetic analyses confirm that the chitin utilization trait was acquired at the root of marine picocyanobacteria. Together this leads us to postulate that attachment to chitin particles allowed benthic cyanobacteria to emulate their mat-based lifestyle in the water column, initiating their expansion into the open ocean, seeding the rise of modern marine ecosystems. Subsequently, transitioning to a constitutive planktonic life without chitin associations led to cellular and genomic streamlining along a major early branch within Prochlorococcus. Our work highlights how the emergence of associations between organisms from different trophic levels, and their coevolution, creates opportunities for colonizing new environments. In this view, the rise of ecological complexity and the expansion of the biosphere are deeply intertwined processes.
