Adeno-Associated Virus Production, Purification, and Titering

Area of Science:

• Molecular Biology
• Gene Therapy
• Neuroscience

Background:

• Adeno-associated virus (AAV) vectors are essential for in vivo gene function studies and gene therapy.
• AAV vectors are particularly suitable for gene transfer into brain tissues.
• Limited availability of AAV hinders its widespread application.

Purpose of the Study:

• To describe a simple, scalable method for adeno-associated virus (AAV) production.
• To provide researchers with ample, high-quality AAV for in vivo gene transfer experiments.

Main Methods:

• Small- to medium-scale production of AAV (10^12 - 10^13 viral particles).
• Utilized Polyethylenimine Max (PEI Max)-mediated triple transfection of HEK 293 cells.
• Purification via iodixanol gradient ultracentrifugation.

Main Results:

• Successfully produced AAV vectors using the described method.
• Achieved production yields suitable for in vivo applications.
• The method provides ample material of sufficient quality for gene transfer.

Conclusions:

• The described method offers a straightforward approach for AAV production.
• This technique addresses the need for readily available, high-quality AAV vectors.
• Facilitates in vivo gene transfer studies and advances gene therapy research.
