Development of sequential sample processing protocol on a single anion-exchange solid-phase extraction disc for bottom-up/cross-linking mass spectrometry

ABSTRACT: In this project, we developed a rapid enzymatic digestion protocol within an anion exchange StageTip named AnExSP (anion-exchange disc-assisted sequential sample preparation) and, using data-independent acquisition, analyzed its digestion performance of human cellular protein extracts (HCPE) using trypsin and trypsin/Lys-C. The outstanding effectiveness and simplicity of AnExSP in sample preparation for gel-based cross-linking mass spectrometry was also verified.

Development of an Automated, Ultra-Rapid Bottom-Up Proteomics Workflow Utilizing Alginate-Based Hydrogels

Project description:A new approach to sample preparation and enzymatic digestion in bottom-up proteomics has been developed using alginate-based hydrogel entrapment of enzymes. This hydrogel facilitates rapid and room-temperature digestions with multienzyme capabilities. Three methodologies were tested: within microcentrifuge tubes, in situ pipette tips, and automated robotic liquid handling. Factorial experimental design identified a 1 h, room temperature, pepsin–trypsin dual-enzyme digestion as optimal for sequence coverage and protein group identification, comparable to a gold-standard overnight proteomic protocol. This method promises significant advancements in proteomic analysis by enhancing reusability, speed, throughput, convenience, and cost-effectiveness, without hindering digestion efficiency.

Modular bottom-up proteomic sample preparation for high-throughput applications

Project description:A collection of digital automated proteomic sample preparation protocols detail three optimized step-by-step methods to: (A) lyse Gram-negative bacteria and fungal cells; (B) quantify the amount of protein extracted; and (C) normalize the amount of protein and set up tryptic digestion. These protocols have been developed to facilitate rapid, low variance sample preparation of hundreds of samples, be easily implemented on widely-available Beckman-Coulter Biomek automated liquid handlers, and allow flexibility for future protocol development

Milk bottom-up proteomics: method optimisation.

Project description:Milk is a complex fluid whose proteome displays a diverse set of proteins of high abundance such as caseins and medium to low abundance whey proteins such as ß-lactoglobulin, lactoferrin, immunoglobulins, glycoproteins, peptide hormones and enzymes. A sample preparation method that enables high reproducibility and throughput is key in reliably identifying proteins present or proteins responding to conditions such as a diet, health or genetics. Using skim milk samples from Jersey and Holstein cows, we compared three extraction procedures which have not previously been applied to samples of cows’ milk. Method A (urea) involved a simple dilution of the milk in a urea-based buffer, method B (TCA/acetone) involved a TCA/acetone precipitation and method C (methanol/chloroform) involved a tri-phasic partition method in chloroform/methanol solution. Protein assays, SDS-PAGE profiling, and trypsin digestion followed by nanoHPLC-electrospray ionisation-tandem mass spectrometry (nLC-ESI-MS/MS) analyses were performed to assess their efficiency. Replicates were used at each analytical step (extraction, digestion, injection) to assess reproducibility. Overall 186 unique accessions, major and minor proteins, were identified with a combination of methods. Method C (methanol/chloroform) yielded the best resolved SDS-patterns and highest protein recovery rates, method A (urea) yielded the greatest number of accessions, and, of the three procedures, method B (TCA/acetone) was the least compatible of all with a wide range of downstream analytical procedures. Our results also highlighted breed differences between the proteins in milk of Jersey and Holstein cows.

On-chip sample preparation using a ChipFilter coupled to NanoLC-MS/MS for bottom-up proteomics

Project description:Sample preparation is a crucial step in bottom-up proteomics. Analytical performances of bottom-up proteomics can be improved by the miniaturization of sample preparation steps. Many microfluidic devices are proposed in the field of proteomics. But many of them are not capable of handling complex sample and do not integrate the processing and digestion steps. We propose a ChipFilter Proteolysis (CFP) microfluidic device derived from the Filter Aided Sample Preparation FASP method for the miniaturization of protein processing and digestion steps in bottom-up proteomics. The microchip has two reaction chambers of 0.6 µL volume separated by a protein filtration membrane in regenerated cellulose. Cell lysis, protein concentration and rapid chemical and enzymatic treatment can be performed in our microfluidic device. Complex proteomic samples like yeast protein extract have already been analyzed with our microchip. Compared to the traditional FASP method, our microfluidic device offers a better proteome coverage with ten times less starting material and eight times quicker protocol.

Expression data from mammary epithelial cells harvested from 8-9 week old C3H female mice - various isolation conditions

Project description:Numerous lineage analysis studies have used FACS sorting as a separation technique prior to measuring mRNA expression patterns. To assess if FACS sorting causes non-specific changes in gene expression, we collected a heterogeneous population of mammary epithelial cells from three biological replicates. We then performed gene expression analysis on each replicate either prior to trypsin digestion, immediately following trypsin digestion, or following both the trypsin digestion and a mock FACS sort. In this dataset, we include gene expression data obtained from isolated murine mammary epithelial cells either prior to trypsin digestion, immediately following trypsin digestion, or following the trypsin digestion and a mock FACS sort.

Differential bottom-up proteomics of truffles

Project description:To compare truffles on protein level, samples of different truffle species (T. magnatum, T. indicum, T. melanosporum, T. aestivum and T. albidum Pico) were analysed by a LC-MS/MS based shotgun proteomics approach. First, different established bottom-up proteomics sample preparation approaches for in solution tryptic proteolysis were tested for a truffle sample. Then, a spectral library was generated by 2D LC-MS/MS and truffle samples were measured in data-independent acquisition (DIA) mode. We provide a comprehensive study on the proteomic differences between truffle species.

Rapid trypsin digestion at elevated temperature with calcium for enhanced bottom-up proteome analysis

Project description:Trypsin is frequently employed to cleave proteins ahead of mass spectrometry characterization. Traditionally, enzyme digestion involves overnight incubation of proteins at 37 °C, which is not only time consuming but can still yield in poor digestion efficiency. While raising the temperature should theoretically accelerate the digestion, this also destabilizes the enzyme and enhances trypsin degradation. We therefore questioned whether elevated temperature digestion is beneficial for improving tryptic digestion. Here we quantify protein digestion kinetics at elevated temperatures for calcium-stabilized trypsin and enforce the critical importance of calcium ions to preserve the enzyme. We quantitatively demonstrate that 1 hour at 47 °C provides a superior digest when compared to conventional (overnight, 37 °C) processing of the proteome. The impact of our enhanced digestion protocol is shown through bottom-up mass spectrometry analysis of a complex proteome mixture.
