Comprehensive Quality Control Strategies for the Baculovirus-Insect Cell Expression System

1. Concept
The baculovirusinsect cell expression system is widely used in biopharmaceuticals for efficient production of complex proteins, vaccines, and viruslike particles. However, it presents unique quality challenges including glycosylation heterogeneity, host cell protein (HCP) impurities, and viral safety risks.

2. Research Frontier
Quality control (QC) has become a core focus for regulatory compliance and drug safety. Advanced mass spectrometry, multitechnology impurity detection, and systematic viral clearance validation are driving nextgeneration process optimization.

3. Research Significance
• Glycosylation directly impacts drug halflife, immunogenicity, and efficacy.
• HCPs may trigger adverse immune reactions and reduce product stability.
• Viral safety validation ensures clinical compliance and patient protection.
• Robust QC supports accelerated approval and industrial scalability.

4. Mechanism and Application
Glycosylation analysis: PNGase F release, 2AB labeling, MALDITOF MS, LCESIMS/MS.
HCP control: ELISA screening + LCMS/MS profiling + MRM quantification.
Viral safety: Indicator viruses, chromatography clearance, lowpH/S/D inactivation.
Applications: Vaccine development, recombinant protein production, ADC manufacturing.
