What is Mass Spectrometry Techniques and Applications?
Mass spectrometry techniques and applications is the set of experimental and computational methods that generate, separate, detect, and interpret gas-phase ions to identify and quantify molecules across chemistry, biology, and materials analysis.
The provided corpus for Mass Spectrometry Techniques and Applications contains 226,044 works (5-year growth: N/A). "MaxQuant enables high peptide identification rates, individualized p.p.b.-range mass accuracies and proteome-wide protein quantification" (2008) is a highly cited example of software-enabled MS proteomics, emphasizing identification, mass accuracy, and quantification in large-scale datasets. Widely used upstream biochemical assays such as "Measurement of protein using bicinchoninic acid" (1985) often support MS workflows by enabling protein amount estimation before digestion and LC–MS analysis.

Why It Matters
Mass spectrometry underpins high-throughput proteomics and quantitative bioanalysis by enabling peptide identification and proteome-wide quantification at scale. Cox and Mann’s "MaxQuant enables high peptide identification rates, individualized p.p.b.-range mass accuracies and proteome-wide protein quantification" (2008) is central to this impact because it formalized a computational approach that links accurate mass measurement to large-scale peptide identification and protein quantification, helping make MS a routine readout for systems biology experiments. In practical laboratory pipelines, protein amount determination prior to digestion is often required for normalization and comparability; "Measurement of protein using bicinchoninic acid" (1985) provides a standardized assay used for this purpose, illustrating how MS results depend on reliable sample preparation and quantification steps. Beyond biomolecules, ion–matter interaction fundamentals are relevant to instrument components and ion behavior in condensed phases; "THE STOPPING AND RANGE OF IONS IN SOLIDS" (1988) is a widely cited reference for ion range and stopping concepts that intersect with MS-adjacent ion physics and detector/material considerations.
Reading Guide
Where to Start
Start with "MaxQuant enables high peptide identification rates, individualized p.p.b.-range mass accuracies and proteome-wide protein quantification" (2008) because it directly connects mass accuracy, peptide identification, and proteome-wide quantification—three pillars of modern MS-based proteomics.
Key Papers Explained
Cox and Mann’s "MaxQuant enables high peptide identification rates, individualized p.p.b.-range mass accuracies and proteome-wide protein quantification" (2008) provides a computational framework for turning MS measurements into peptide IDs and quantitative protein tables. Smith et al.’s "Measurement of protein using bicinchoninic acid" (1985) complements this by supporting upstream protein quantification for normalization and controlled sample input prior to LC–MS analysis. Ziegler’s "THE STOPPING AND RANGE OF IONS IN SOLIDS" (1988) adds ion–matter interaction fundamentals that connect to how ions interact with materials, which is relevant when reasoning about ion handling and detection in ion-based analytical instrumentation.

Advanced Directions
Within the constraints of the provided paper list, the clearest advanced direction is deeper integration of computational pipelines for identification and quantification as exemplified by "MaxQuant enables high peptide identification rates, individualized p.p.b.-range mass accuracies and proteome-wide protein quantification" (2008), alongside rigorous upstream quantification controls as in "Measurement of protein using bicinchoninic acid" (1985). A second frontier is connecting ion–matter interaction knowledge ("THE STOPPING AND RANGE OF IONS IN SOLIDS" (1988)) to practical instrument design and stability considerations when interpreting ion trajectories and interactions with solid components.

Frequently Asked Questions
What is the core goal of mass spectrometry in proteomics workflows?
In MS-based proteomics, the core goal is to identify peptides (and infer proteins) and quantify them across samples using measured ion signals and accurate mass information. "MaxQuant enables high peptide identification rates, individualized p.p.b.-range mass accuracies and proteome-wide protein quantification" (2008) explicitly frames this goal as achieving high identification rates together with p.p.b.-range mass accuracies and proteome-wide quantification.
How does computational analysis influence peptide identification and quantification from LC–MS data?
Computational analysis determines how raw spectra are matched to peptide sequences, how features are aligned across runs, and how quantitative signals are aggregated to proteins. Cox and Mann’s "MaxQuant enables high peptide identification rates, individualized p.p.b.-range mass accuracies and proteome-wide protein quantification" (2008) is a canonical example showing that software design can simultaneously improve identification rates, mass accuracy, and proteome-wide quantification.
Why do many MS experiments measure total protein before running LC–MS/MS?
Total protein measurement supports normalization (e.g., equal loading) and helps control variability introduced during digestion and sample handling. "Measurement of protein using bicinchoninic acid" (1985) is a standard approach for estimating protein concentration that can be used as an upstream control in MS proteomics workflows.
Which highly cited paper in the provided list is most directly connected to mass-spectrometry-based proteomics data processing?
"MaxQuant enables high peptide identification rates, individualized p.p.b.-range mass accuracies and proteome-wide protein quantification" (2008) is the most directly MS-proteomics-focused paper in the provided top-cited list. Its title explicitly targets peptide identification, p.p.b.-range mass accuracy, and proteome-wide protein quantification.
Which references in the provided list are relevant for interpreting ion behavior beyond biomolecular identification?
"THE STOPPING AND RANGE OF IONS IN SOLIDS" (1988) is relevant for understanding how ions lose energy and propagate in solid materials, which connects to detector and material interactions in ion-based measurements. While not a proteomics workflow paper, it addresses ion–solid interaction concepts that can matter when considering instrument physics and materials.
