Peptidomics-Based Biological Research Service
Peptidomics is a branch of proteomics that focuses on the comprehensive study of endogenous peptides within biological systems. These short amino acid sequences function as hormones, neurotransmitters, signaling messengers, antimicrobial agents, and modulators of immune responses. Unlike proteomics, which primarily analyzes large intact proteins, peptidomics provides a focused lens on smaller functional peptide species that often act as immediate effectors of physiological processes. Understanding peptide composition and dynamics is essential for elucidating mechanisms involved in growth regulation, metabolism, immune response, cellular communication, and disease progression. In biological systems, peptides are increasingly recognized as critical mediators of development and stress adaptation. From discovering new biomarkers in neurodegenerative diseases to identifying peptide-based regulators in crop resistance, peptidomics enables a wide spectrum of biological research and translational applications.

Analysis Workflow
1. Sample Collection and Preparation: The first step involves the collection of biological samples. Samples are processed to extract peptides while minimizing contamination from high-molecular-weight proteins.
2. Peptide Extraction and Enrichment: Peptides are isolated from the biological sample using optimized extraction protocols, which include solid-phase extraction or liquid-liquid extraction techniques. Enrichment strategies may be employed to concentrate low-abundance peptides and reduce sample complexity.
3. Mass Spectrometry Analysis: Extracted peptides undergo analysis using high-resolution mass spectrometry systems. The MS analysis provides detailed peptide sequencing, identification, and quantification, enabling us to obtain comprehensive peptidomics profiles.
4. Data Processing and Interpretation: The raw MS data is processed using advanced bioinformatics tools to identify peptides, quantify their abundance, and analyze post-translational modifications (PTMs). This step also includes peptide mapping and functional annotation.
5. Functional and Pathway Analysis: Identified peptides are mapped to specific biological pathways and molecular functions using gene ontology (GO) terms and KEGG pathway annotations. Protein-protein interaction networks are also constructed to further understand peptide roles in cellular processes.
6. Results Reporting: A detailed report is generated, summarizing key findings such as peptide identification, quantification, PTM analysis, and biological interpretations. This includes visualizations, functional annotations, and relevant pathways for a comprehensive understanding of the data.
