Protein Therapeutics Analysis Workflows

Význam tématu:
Protein therapeutics have become a cornerstone of modern biopharmaceutical development due to their ability to target complex biological functions with high specificity. Rigorous analytical characterization during discovery, process development, characterization, and quality control ensures product safety, efficacy, and regulatory compliance.

Cíle a přehled studie / článku:
This document outlines a comprehensive suite of analytical workflows designed to monitor the critical quality attributes of protein biologics from early discovery through commercial manufacturing. Key areas include intact and native mass analysis, aggregate profiling, subunit mapping, higher order structure assessment, charge variant detection, peptide mapping, multi-attribute monitoring, host cell protein analysis, and glycan profiling.

Použitá metodika a instrumentace:

• Orbitrap Exploris and Q Exactive Orbitrap MS platforms for high-resolution intact mass and subunit analysis
