Microwave‐Accelerated Proteolysis Minimizes Artificial Deamidation and Enhances Speed for Peptide Mapping of Protein Pharmaceuticals

Key Points

The aim is to reduce artificial deamidation during peptide mapping and improve efficiency in protein pharmaceuticals.
Utilized microwave-accelerated proteolysis under optimized Tris buffer conditions
Compared digestion times before and after microwave application
Analyzed effects on artificial deamidation in IgG and BSA proteins
Reduced digestion time from 16-18 hours to minutes
Lowered artificial deamidation by approximately 60%-80%
Findings in IgG and BSA indicate consistency and reliability for quality assessments

Abstract

Microwave-accelerated proteolysis under optimized Tris buffer conditions minimizes artificial N/Q deamidation during peptide mapping while substantially reducing preparation time. Digestion time decreases from 16-18 h to minutes, lowering deamidation by ~60%-80%. Consistent findings in IgG and BSA improve confidence in CQA assessment and support high-throughput biopharmaceutical quality control.
