Advancements in Peptide Mapping for Protein Characterization
Received Date: Nov 03, 2025 / Published Date: Dec 01, 2025
Abstract
Recent advancements in peptide mapping methodologies are revolutionizing protein characterization. Techniques such as high-throughput capillary-liquid chromatography-mass spectrometry, multi-attribute peptide mapping, and novel data-independent acquisition strategies enhance sensitivity, throughput, and comprehensive identification of peptides and post-translational modifications. Innovations in trapped ion mobility spectrometry-mass spectrometry and microfluidic platforms streamline workflows and reduce analysis time. Deep learning applications improve data analysis accuracy, while combined top-down/bottom-up approaches offer detailed antibody characterization. Automated systems increase efficiency, and capillary electrophoresis-mass spectrometry provides superior resolution for complex mixtures. These developments collectively advance biopharmaceutical quality control and fundamental protein biology.
