Peptides are not only intermediate products generated during protein degradation but also a crucial class of regulatory molecules involved in various biological processes. They participate in key pathways such as signal transduction, metabolic regulation, immune responses, and the onset and progression of diseases. Nevertheless, peptide-focused research has long faced significant challenges: peptides in biological samples are highly heterogeneous, their abundance spans a wide dynamic range, and they exhibit diverse modification patterns. Conventional chromatography- and immunoassay-based techniques have limited sensitivity, resolution, and throughput, making it difficult to achieve comprehensive and high-precision profiling of peptides in complex biological matrices.
With high-resolution mass spectrometry (MS), researchers can perform systematic qualitative and quantitative profiling of endogenous peptides in biological specimens, enabling a deeper understanding of their functional roles in physiological and pathological contexts. Leveraging its state-of-the-art mass spectrometry platform and integrated bioinformatics analysis workflow, MtoZ Biolabs has established a one-stop Peptideomics Analysis service that covers the entire process from sample preparation to data interpretation, providing high-quality technical support for academic institutions and pharmaceutical enterprises, and empowering every stage of peptide research.
What is Peptideomics?
1. Research Objectives of Peptideomics
Peptideomics is a discipline centered on mass spectrometry that systematically investigates endogenous peptides within biological systems. Its objectives extend beyond identifying naturally occurring peptides to quantifying their dynamic expression across different biological states. Unlike Proteomics, which typically involves enzymatic digestion prior to analysis, peptideomics directly examines undigested samples, preserving native peptide states and minimizing artifacts introduced during proteolysis. This approach yields data that more faithfully reflect in vivo peptide profiles and provides powerful insights into regulatory pathways, molecular signaling, and disease mechanisms.
Mass Spectrometry-Based Peptide Analysis
1. Principles of Mass Spectrometry-Based Peptide Analysis
Mass spectrometry (MS) is fundamentally based on the measurement of the mass-to-charge ratio (m/z) of molecular ions, enabling precise identification of peptide species. In peptideomics, MS not only provides accurate molecular mass information but also elucidates peptide sequences and post-translational modifications. Typically, primary MS (MS¹) measures the overall mass distribution of peptides in a given sample, whereas tandem MS (MS² or MS/MS) infers amino acid sequences by analyzing fragment ion spectra. The integration of these two analytical dimensions allows the high-resolution detection and characterization of thousands of peptides within a remarkably short analytical timeframe.
2. General Workflow for Peptide Identification Using Mass Spectrometry
Reliable peptide analysis requires meticulous sample preparation and standardized experimental protocols, typically encompassing the following steps:
（1）Sample Preprocessing
Physical or chemical separation methods (such as size-exclusion chromatography or solid-phase extraction) are employed to remove high-abundance proteins and enrich target peptides.
（2）Peptide Detection
Liquid chromatography coupled with tandem mass spectrometry (LC-MS/MS) is utilized for high-throughput peptide detection.
（3）Data Analysis
Specialized bioinformatics algorithms are applied for peptide sequence identification and quantitative expression profiling.
The overall reliability of MS-based results depends on instrumental resolution, ionization efficiency, and signal stability, while algorithmic precision determines the depth and accuracy of peptide identification. Combined with label-based or label-free quantification and automated data-processing pipelines, researchers can rapidly obtain comprehensive and biologically meaningful peptide datasets.
