What Is Peptide Characterization?
Peptide characterization refers to the detailed study and analysis of peptide molecules to confirm their structure, composition, and biological activity. Since peptides are made up of amino acids linked by peptide bonds, any variation in structure or purity can impact their effectiveness. Therefore, understanding every detail of a peptide is essential before it can be used in medical treatments or diagnostics.
Peptide characterization uses advanced techniques to confirm that a peptide is accurate, pure, and safe. It also checks how the peptide performs under different conditions, like temperature or pH changes. At ResolveMass, we use validated, regulatory-approved methods to deliver reliable and precise results. Our data meets international standards, including those from the FDA, EMA, and Health Canada. We work closely with clients from early research stages to final regulatory submissions. Each peptide is carefully analyzed to support its use in both clinical trials and commercial products.
Why Is Peptide Characterization Important?
Peptide characterization is more than just a routine test. It plays a critical role in making sure peptide-based drugs are safe, effective, and consistent. With peptides used in sensitive therapies, such as cancer treatments and vaccines, even small errors can have serious effects on patient safety and product performance.
One of the main reasons for detailed peptide analysis is to meet the strict requirements of regulatory agencies. Organizations like the FDA need reliable data for IND and NDA submissions. Peptide characterization also ensures that each production batch stays consistent in quality and structure, which supports stable therapeutic results. Advanced testing helps detect impurities and degradation early, reducing risks during development. Overall, this process improves product stability and builds confidence in the safety and effectiveness of peptide-based drugs.

Core Peptide Characterization Techniques and Applications
At ResolveMass, we use a combination of techniques to perform peptide characterization with the highest accuracy. These methods are chosen based on the peptide’s structure, use, and development stage. Each technique helps provide a complete view of the peptide’s quality.
1. Mass Spectrometry (MS)
Mass spectrometry is a powerful tool used to determine the molecular weight and identity of peptides. It helps detect even small impurities or changes in the peptide structure. Our lab uses both LC-MS/MS and high-resolution MS systems for in-depth analysis.
We apply MS to confirm peptide sequence, identify post-translational modifications, and analyze degradation patterns. This information is especially useful when preparing data for regulatory submissions or troubleshooting formulation issues.

2. High-Performance Liquid Chromatography (HPLC)
HPLC is a standard method used to separate and analyze the components of a peptide mixture. It is essential for checking peptide purity and identifying unwanted by-products or isomers. Our lab uses validated protocols that are tailored to regulatory standards.
We utilize both reverse-phase and ion-exchange HPLC techniques to deliver precise results. This helps researchers and developers confirm that their peptides meet purity and safety requirements before moving to clinical stages.
3. Amino Acid Analysis
Amino acid analysis provides information about the number and type of amino acids present in a peptide. This is important to confirm the correct peptide composition and synthesis accuracy. At ResolveMass, we use derivatization and UV detection to ensure precise measurements.
This technique is especially useful for confirming the success of peptide synthesis. It can also help detect any missing or extra amino acids that may affect the peptide’s performance or stability.
4. Circular Dichroism (CD) Spectroscopy
CD spectroscopy helps analyze the secondary structure and folding behavior of peptides. Knowing how a peptide folds is critical because its structure often determines how well it functions in the body.
We combine CD with other methods like FTIR (Fourier-transform infrared spectroscopy) to study peptide stability under different pH levels, temperatures, or storage conditions. This helps in designing stable formulations and predicting shelf life.
5. Peptide Mapping
Peptide mapping is used to verify the sequence of the peptide and check for any structural inconsistencies. It involves breaking down the peptide using enzymes and analyzing the resulting fragments.
This method helps ensure the peptide was synthesized correctly and is especially important when submitting data to regulatory authorities. At ResolveMass, we perform peptide mapping using high-quality enzymatic digestion and analysis tools.
