Peptide analysis

Analytic services for peptide identity

Do you want the ID, N-terminal sequence, or exact MW of an unknown peptide in your sample? Perhaps you even want to analyze hundreds of peptides in a sample at once?

Or maybe your goal is to determine the quantity of the peptide and its process-related impurities (like host cell proteins and other residuals)?

Then, mass spectrometry-based me...

Do you want the ID, N-terminal sequence, or exact MW of an unknown peptide in your sample? Perhaps you even want to analyze hundreds of peptides in a sample at once?

Or maybe your goal is to determine the quantity of the peptide and its process-related impurities (like host cell proteins and other residuals)?

Then, mass spectrometry-based methods are the right solution for you. With our results, you can optimize the development and manufacturing of your peptide. Within weeks you can speed up your project timeline by reducing unnecessary purification matrices, pinpoint weak points in your processes and gain valuable insight in your product’s content, stability, and function.

Alphalyse offers full characterization of your unique peptide-based biologic by mass spectrometry. We utilize nanoLC-MS/MS for the analysis if the purified peptide is of low abundance. Consequently, we can analyze your sample even if the sample amount is limited. All tests are performed according to the ICH Q6B guidelines – Test Procedures and Acceptance Criteria for Biotechnological/Biological Products and rely on pipetting robots, strict SOPs and extensive cross-training among laboratory staff.

You can choose and combine your preferred peptide analysis package from the services below:

More info

Peptides are increasingly used as the active pharmaceutical ingredient (API) in biologics, and we conduct more and more characterization projects of biological peptides. Typical analyses of peptide therapeutics investigate the peptide identity, sequence, heterogeneity, intact mass, stability, degradation products, quantity of individual amino acids, etc.

Comprehensive analytical characterization of a peptide drug product is needed to achieve regulatory approval, as well as define and monitor critical quality attributes (CQA).

Our experience with peptides is closely connected and updated by a strong collaboration with the Protein Research Group at the University of Southern Denmark (SDU), world famous for its proteomics and protein research.

Who is this for?

We primarily help customers within the pharmaceutical industry, and biotechs working on drug development, e.g.

Project managers

Working with process development and characterization projects.

Analytical experts

Protein scientists that work with elisa, masss spectrometry, or CMC.
