Combining steric exclusion with anion exchange - development of a universal and scalable adeno-associated virus downstream process.

Adeno-associated viruses (AAV) are among the leading vectors for in vivo gene therapy. The purification of AAV remains a bottleneck as it typically requires multiple individual process steps, often resulting in product loss and high costs. Current downstream processes are usually serotype-specific and rely primarily on expensive affinity resins.

A Novel and Simplified Anion Exchange Flow-Through Polishing Approach for the Separation of Full From Empty Adeno-Associated Virus Capsids.

Adeno-associated viruses (AAV) are widely used viral vectors for in vivo gene therapy. The purification of AAV, particularly the separation of genome-containing from empty AAV capsids, is usually time-consuming and requires expensive equipment. In this study, we present a novel laboratory scale anion exchange flow-through polishing method designed to separate full and empty AAV.

Unveiling the secrets of adeno-associated virus: novel high-throughput approaches for the quantification of multiple serotypes.

Adeno-associated virus (AAV) vectors are among the most prominent viral vectors for gene therapy, and their investigation and development using high-throughput techniques have gained increasing interest. However, sample throughput remains a bottleneck in most analytical assays. In this study, we compared commonly used analytical methods for AAV genome titer, capsid titer, and transducing titer determination with advanced methods using AAV2, AAV5, and AAV8 as representative examples.

A robust and efficient alluvial filtration method for the clarification of adeno-associated viruses from crude cell lysates.

Adeno-associated virus (AAV) based vectors have recently been gaining importance as DNA delivery systems. Efficient downstream processing of AAV remains a major challenge as serotypes differ in physicochemical properties, making it difficult to design uniform purification processes. Clarification of AAV is an especially critical step.
