Boston, MA, United States, 1st May 2025 - 4D proteomics service is an advanced analytical offering designed to push the boundaries of protein characterization through enhanced separation, sensitivity, and speed. Built upon conventional 3D proteomics (retention time, mass-to-charge ratio, and intensity), 4D proteomics introduces ion mobility as a fourth dimension, enabling precise separation of peptide ions based on their collisional cross-section and shape. This concept gained momentum in 2018 with the launch of the Bruker timsTOF Pro system, which integrates Trapped Ion Mobility Spectrometry (TIMS) and Parallel Accumulation–Serial Fragmentation (PASEF) technologies. Together, these innovations significantly improve the detection of low-abundance proteins and the resolution of post-translational modification (PTM) isomers, offering an unparalleled depth of proteomic analysis.
To meet the growing demand for high-throughput, modification-aware proteomics from limited sample input, MtoZ Biolabs has launched a dedicated 4D proteomics service powered by the timsTOF Pro platform. Our streamlined workflow translates complex ion mobility data into high-confidence proteomic insights, enabling researchers to explore dynamic proteome changes with exceptional clarity. Whether for biomarker discovery, drug mechanism investigation, systems biology, or clinical metaproteomics, MtoZ Biolabs delivers expert-guided, scalable solutions that accelerate your research with precision and reliability.
Beyond adding ion mobility as a fourth analytical dimension, 4D proteomics fundamentally redefines how proteomic data is acquired and interpreted. Unlike conventional workflows that may suffer from peptide co-elution, signal interference, or limited depth, 4D proteomics enhances analytical resolution and throughput through precise ion separation and high-speed MS/MS sequencing. Key performance advantages of 4D proteomics include:
Together, these attributes translate into deeper proteome coverage, improved confidence in peptide identification, and enhanced ability to resolve post-translational modification variants—all critical for systems biology, clinical research, and biomarker-driven studies.
The combination of high resolution, speed, and reproducibility makes 4D proteomics analysis uniquely suited for a variety of scientific applications:
In disease research, particularly oncology and neurology, sensitivity is paramount. 4D proteomics allows for confident identification and quantification of differentially expressed proteins in limited patient samples—accelerating biomarker validation in multi-sample clinical studies.
By quantifying proteome dynamics under drug treatment or gene modulation (e.g., knockout, knockdown, or overexpression), researchers can map signaling pathways, monitor off-target effects, and evaluate downstream consequences of therapeutic interventions.
From studying drought resistance in crops to characterizing microbiome shifts in polluted ecosystems, 4D proteomics enables the tracking of subtle protein expression changes, even from trace biological samples like plant exudates or microbial pellets.
With its ability to differentiate between similar peptides and modification isomers, 4D proteomics is ideally positioned to support large-scale PTM mapping projects. Phosphorylation, glycosylation, acetylation, and ubiquitination can be tracked at high throughput and high site resolution.
To address a wide range of proteomic research needs—from global expression profiling to site-specific modification analysis and microbial community studies—MtoZ Biolabs offers a suite of specialized 4D proteomics service modules. These modules are designed to fully leverage the advantages of ion mobility-enhanced mass spectrometry, while maintaining flexibility, depth, and scalability.
Modules: 4D Label-Free Quantification (4D-LFQ), 4D Data-Independent Acquisition (4D-DIA) These foundational modules support comprehensive protein expression analysis across multiple samples, conditions, or timepoints.
Modules: 4D-PTMomics, 4D Glycoproteomics and Glycoform Profiling
These modules focus on high-resolution, site-specific identification of regulatory modifications that control protein function and signaling.
Module: 4D Metaproteomics
Tailored for complex biological mixtures, this module enables species- and function-level protein identification from microbiomes and multispecies samples.
The enhanced separation capacity of 4D proteomics allows accurate detection of microbial proteins in challenging matrices such as stool, soil, fermentation broth, or biofilms—without the need for extensive sample cleanup.
MtoZ Biolabs accommodates a wide range of biological matrices to support diverse research scenarios, from clinical trials to basic discovery projects. Our 4D proteomics service is optimized
for high sensitivity and low input volumes, making it ideal for projects involving precious or limited samples.
Supported Sample Types:
Transport Instructions: All samples should be shipped on dry ice with proper insulation. We recommend using an express courier to reduce freeze-thaw cycles and degradation risk. Samples with high SDS or salt concentrations may require buffer exchange prior to processing—please consult our technical support team for guidance.
