What is Peptide Mapping in Biopharmaceuticals?

Peptide mapping in biopharmaceuticals is a method used to break down proteins into smaller peptide fragments and analysing their sequences through techniques such as mass spectrometry and HPLC. This provide scientists to verify the primary structure of biopharmaceutical products and identify any possible modifications or contaminants.
Our Peptide Sequencing Service ensures the utmost accuracy in mapping outcomes.

Why is Peptide Mapping in Biopharmaceuticals Essential for Quality Control?

Peptide mapping in biopharmaceuticals is not just a routine examination — it is a regulatory mandate. Authorities such as FDA and EMA require thorough structural characterization of therapeutic proteins.

key reasons include:

Identity Confirmation: confirms the biopharmaceuticals matches the intended protein sequence.
Purity Assessment: Detects contaminants and impurities related to manufacturing process.
Stability Evaluation: Tracks degradation, oxidation, deamidation, and other post-translational modifications.
Batch-to-Batch Consistency: Ensures reproducibility in every production lot.
