virus purification

In recent years, gene therapy treatments have increased significantly, requiring more efficient processes to purify and deliver these therapeutics. Lentiviral vectors (LVVs) are a type of retrovirus and are an effective tool for gene delivery. In this webinar, data are shown for a high-throughput screening strategy that was employed for LVV purification, which provided high yield as well as acceptable host cell protein (HCP) clearance.

Large molecule purification presents significant challenges due to their considerable size. For instance, Immunoglobulin M (IgM) molecules, ranging from 900 to 1,000 kD, play pivotal roles in mammalian immune responses and find extensive applications in diagnostics and therapeutics. Purification of such molecules is particularly intricate owing to several factors including their weak Protein A binding sites, limited dynamic binding capacity, and slow diffusion rates.

Anion exchange and mixed-mode chromatography offer efficient and flexible AAV purification. Learn new strategies for optimizing viral vector purification.

A new and simplified anion exchange chromatographic process for the purification of both live and inactivated cell grown H1N1 influenza viruses was established with a recently developed anion exchanger. The resin is designed with an optimized surface extender and pore size for superior accessibility and large biomolecule binding capacity, aiming to overcome common drawbacks of existing ion exchangers for virus purification.

Learn how a team developed a single-step workflow for column purification of the Influenza A H1N1 subtype using the recently developed Nuvia HP-Q Anion Exchange Resin. This protocol is scalable, efficient, and produced good yields with high purity.
