Understanding the Importance of Synthetic Peptide Characterization
Synthetic peptides are increasingly used in therapeutics, diagnostics, and vaccine innovation. However, their complex structures and vulnerability to degradation require robust Synthetic Peptide Characterization to:
- verify sequence accuracy
- Detect impurities
- Analyze post-synthesis modifications
- Ensure batch-to-batch consistency
Collaborating with ResolveMass Laboratories Inc. means your peptides undergo the most rigorous and state-of-the-art Characterization protocols.

Recent Advancements in Synthetic Peptide Characterization Technologies
1. High-Resolution Mass Spectrometry (HRMS)
Recent enhancements in HRMS provide Synthetic Peptide Characterization with unmatched sensitivity and mass accuracy. Orbitrap and FT-ICR platforms offers resolution capable of distinguishing even subtle chemical variants, ensuring In-depth impurity profiling.
2. Top-Down and Middle-Down Proteomics Techniques
Rather than breaking peptides into smaller fragments, top-down and middle-down approaches analyze intact or partially digested synthetic peptides, preserving complete information about modifications, folding, and disulfide bonds.
3. Ion Mobility Spectrometry (IMS)
IMS enhances Synthetic Peptide Characterization by separating conformers based on their gas-phase mobility, allowing better differentiation between isobaric and isomeric species.
4. Enhanced Peptide Mapping Techniques
ResolveMass integrates automated enzymatic digestion with advanced LC-MS/MS mapping, delivering a detailed fingerprint of synthetic peptides for sequence confirmation and impurity detection..

5. Multi-Attribute Method (MAM)
MAM is quickly becoming the gold standard, where a single LC-MS analysis simultaneously covers identification, quantification of critical quality attributes (CQAs), and impurity detection for synthetic peptides.
Case Study: Solving Sequence Misincorporation in Synthetic Peptide Batches
Background
A leading biotechnology firm approached ResolveMass Laboratories Inc. after encountering unexplained batch failures of a synthetic peptide vaccine candidate.
- Peptide length: 18 amino acids
- Target purity: 99%
- Problem: Unexpected peaks observed during QC HPLC testing
Strategy and Execution
ResolveMass applied advanced Peptide Characterization methodologies:
- Orbitrap HRMS identified an aberrant +14 Da mass shift corresponding to misincorporation of a leucine instead of valine at position 7.
- Top-Down LC-MS/MS pinpointed the substitution location without requiring full digestion.
- Orthogonal Peptide Mapping validated the findings using different enzymes (trypsin and Glu-C).
- Stability testing showed misincorporated peptides degraded faster under stress (30% potency loss after 1 month at 40°C)..
Results
| Parameter | Before Investigation | After ResolveMass Analysis |
|---|---|---|
| Misincorporation Rate | ~2.5% | Eliminated (confirmed <0.05%) |
| Stability under Stress | 70% potency retention | >95% potency retention |
| Regulatory Filing Risk | High | Mitigated |
Thanks to this comprehensive Synthetic Peptide Characterization, the client corrected their manufacturing process and confidently advanced their regulatory filings.
