Bacteria Peptidomics Analysis Service
Bacterial peptidomics is a systematic approach that focuses on the comprehensive identification and characterization of naturally occurring short peptides in bacterial cells. Unlike conventional proteomics, which primarily analyzes enzymatically digested peptides, peptidomics directly targets endogenous peptides—including degradation intermediates, antimicrobial peptides, signaling peptides, and virulence-related fragments—providing a more immediate and functional snapshot of bacterial physiology.
In bacterial research, peptidomics is widely employed to investigate stress responses, virulence factor secretion, antimicrobial activity, and host–microbe interactions. Compared to full-proteome analysis, peptidomics offers higher temporal resolution and functional specificity, revealing insights into metabolic activity, protein processing pathways, and microbial ecology.
As a specialized CRO in multi-omics research, MtoZ Biolabs leverages advanced mass spectrometry platforms such as Orbitrap Fusion Lumos and Q Exactive HF, combined with extensive experience in microbiological studies, to deliver high-resolution, in-depth Bacteria Peptidomics Analysis Service that accelerates microbiology, drug discovery, and systems biology research.
Services at MtoZ Biolabs
MtoZ Biolabs’ Bacteria Peptidomics Analysis Service integrates multiple sample preparation strategies—including molecular weight cutoff filtration, acid extraction, and reverse-phase purification—with high-resolution LC-MS/MS platforms to accurately identify endogenous peptides in bacterial samples. These include functional peptides, antimicrobial peptides, signaling peptides, toxin-associated peptides, siderophores, and post-translationally modified peptides. The service encompasses comprehensive peptidome profiling, differential peptide expression analysis, pathway enrichment annotation, customized analysis of specific peptide classes, and optional multi-omics integration to provide an in-depth understanding of bacterial metabolic states and regulatory mechanisms.
