Abstract:
Virus-like particles (VLPs) of the adeno-associated virus (AAV) can be produced using the baculovirus expression vector system. Insertion of small peptides on the surface of the AAV or AAV VLPs has been used to redirect the AAV to different target tissues and for vaccine development. Usually, the VLPs self-assemble intracellularly, and an extraction step must be performed before purification. Here, we describe the method we have used to extract AAV VLPs from insect cells successfully with peptide insertions on their surface.
