Adeno-Associated Virus (AAV)

Adeno-associated virus (AAV) purification is a critical step in the production and application of AAV vectors, which have become essential tools in gene therapy and genetic research. AAVs are known for their safety, efficiency, and long-lasting gene expression, but the presence of impurities in AAV preparations can hinder their therapeutic and research potential. Purification processes, often involving chromatography and ultracentrifugation, help concentrate and isolate AAV particles while removing contaminants such as cellular debris, other viral particles, and host cell proteins. This purification ensures that AAV vector preparations are of high purity and potency, minimizing the risk of adverse immune responses and enhancing the precision of gene delivery. AAV purification is vital for developing safe and effective gene therapies and for conducting precise genetic studies, making it a cornerstone of the rapidly evolving field of gene-based medicine and genetic research.
