Utilizing Retrovirus-Like Particles (RVLP) To Evaluate Viral Clearance For Multiple Modes Of Separation

By David Cetlin, senior director, MockV® products

Viral clearance studies are critical in ensuring the safety of biopharmaceutical products. Traditional methods often rely on infectious viruses, posing safety concerns and limitations. This poster introduces a novel approach using retrovirus-like particles (RVLPs) as a safe and effective alternative.

RVLP Production and Characterization

RVLPs are non-infectious particles that mimic the structure and behavior of retroviruses. They are produced in CHO cells and purified through various chromatographic methods. The poster presents data on RVLP production, purification, and characterization, including size and morphology analysis.

RVLPs in Viral Clearance Studies

The poster highlights the application of RVLPs in evaluating viral clearance for different separation modes, including:

• Viral Filtration
• Anion Exchange Chromatography
• Protein A Chromatography
• Hydrophobic Interaction Chromatography
• Cation Exchange Chromatography
• Mixed Mode Chromatography

Advantages of RVLPs

RVLPs offer several advantages over traditional methods, including:

• Safety: RVLPs are non-infectious, eliminating the risks associated with handling live viruses.
• Versatility: RVLPs can be used to evaluate various separation modes and process conditions.
• Sensitivity: RVLPs can be detected with high sensitivity using molecular methods.
• Relevance: RVLPs closely resemble retroviruses, providing relevant insights into viral clearance mechanisms.

RVLPs represent a promising tool for viral clearance studies, offering a safer, more versatile, and sensitive alternative to traditional methods. Their use can enhance the safety and efficiency of biopharmaceutical manufacturing processes.
