Background:

• MS2 virus-like particles (VLPs) are crucial for nanotechnology and drug delivery.
• Current VLP disassembly and reassembly protocols lack standardization, hindering reliable cargo encapsulation.

Purpose of the Study:

• To systematically assess and optimize MS2 VLP disassembly and reassembly techniques.
• To establish a standardized framework for quantifying VLP reassembly yield.
• To identify key experimental factors influencing VLP reassembly efficiency.

Main Methods:

• Optimization of acid-based disassembly and acid removal.
• Development of a standardized reassembly yield quantification framework using size exclusion chromatography.
• Full-factorial design of experiments to evaluate the impact of pH, sodium chloride concentration, and crowding agents on reassembly.

Main Results:

• Optimized acid-based methods offer trade-offs between speed, recovery, and accessibility.
• High sodium chloride concentration significantly inhibits MS2 VLP reassembly efficiency.
• pH and crowding agents have minor effects on reassembly yield, with optimal conditions potentially extending beyond current experimental ranges.

Conclusions:

• Provides practical guidelines and a reproducible framework for MS2 VLP disassembly and reassembly.
• Enables more reliable and efficient encapsulation strategies for diverse applications.
• Highlights the critical role of salt concentration in VLP reassembly processes.
