Serum Peptidomics Service

MtoZ Biolabs provides professional serum peptidomics service based on standardized sample processing strategies and high-resolution mass spectrometry technologies to perform systematic identification and quantification of endogenous serum peptides. This service assists research institutions and biopharmaceutical companies in analyzing peptide changes in vivo for disease mechanism studies, biomarker discovery, and drug response monitoring. The goal is to provide high-quality and reproducible serum peptide data to ensure smooth downstream research.

 

Why Serum Peptidomics Matters

Serum peptidomics uses high-resolution mass spectrometry to analyze naturally occurring low molecular weight peptides in serum, providing molecular information that reflects proteolysis, inflammation, metabolic regulation, and tissue injury. Endogenous peptides are highly sensitive to physiological and pathological changes and often fluctuate at very early stages of disease, making them valuable indicators for biomarker discovery, mechanism studies, and drug response monitoring.

 

However, the serum matrix is extremely complex. High-abundance proteins can mask low-abundance peptides, and small peptides are short, low in concentration, and unstable, making them easily affected by sampling and processing conditions. Individual variability further increases the analytical challenges. Therefore, high-quality serum peptidomics requires standardized sample preprocessing, high-sensitivity mass spectrometry platforms, and data analysis workflows tailored to the characteristics of endogenous peptides to ensure reliable and interpretable results.

 

Serum Peptidomics Service at MtoZ Biolabs

☑️ Identifies and quantifies endogenous serum peptides by analyzing thousands of naturally occurring peptides to discover new bioactive molecules or accurately measure the expression levels of known peptides.

☑️ Removes high-abundance serum proteins to reduce interference from albumin and immunoglobulins, enhancing the detection sensitivity of low-abundance regulatory and disease-related peptides.

☑️ Enriches low molecular weight peptide components through optimized extraction and purification strategies to retain physiologically relevant peptides and minimize sample degradation.

☑️ Analyzes and interprets peptidomics data using specialized bioinformatics workflows to identify differential patterns, extract sequence features, associate potential pathways, and generate clear publication-ready reports.

☑️ Monitors drug-induced peptide changes by comparing peptide profiles between treated and control groups, evaluating alterations in protease and peptidase activity for drug response studies, mechanism verification, and efficacy assessment.

Q3: How should I prepare my samples?

To ensure accurate and reproducible results for the Serum Peptidomics Service, MtoZ Biolabs recommends the following preparation guidelines:

1. Sample Type: We accept human or animal serum processed under standard clinical or laboratory procedures. Avoid hemolyzed or lipemic samples as they may affect peptidomic profiling.

2. Sample Quality: Samples should be clear and free of particulate matter. Avoid detergents, protease inhibitors, or buffers that may interfere with endogenous peptide extraction.

3. Volume Requirement: Provide at least 200 μL of serum per sample. Additional volume may be required for deeper analysis, technical replicates, or optional fractionation.

4. Storage and Shipping: Store serum at −80°C immediately after processing. Ship samples on dry ice in leak-proof containers to maintain integrity and prevent degradation of endogenous peptides.

5. Documentation: Include information such as sample origin, collection time, fasting status, preparation method, storage conditions, grouping information, and desired analysis depth.
