AAV Vector Production (AAV Plasmid Synthesis)

 

AAV Vector Production service provides the synthesis and cloning of transgene expression cassettes into custom AAV vectors with high efficiencies. Utilizing our decade-plus experience in synthesizing DNA, GENEWIZ from Azenta Life Sciences has developed a unique adeno-associated virus vector production service, the first of its kind, for researchers working with adeno-associated virus vectors. GENEWIZ AAV Vector Production service, listed as AAV Plasmid Synthesis in our CLIMS4 ordering system, comes bundled with our AAV Plasmid Preparation protocol to deliver mini- to giga-scale AAV plasmids that have been sequence-verified by our AAV-ITR Sanger Sequencing service.

We understand the importance of intact inverted terminal repeat (ITR) regions in downstream AAV gene therapy applications. GENEWIZ maintains a 2-step QC process and ITR correction by gene synthesis to ensure the integrity of your ITR regions.

GENEWIZ INVERTED TERMINAL REPEAT (ITR) CORRECTION

Original AAV inverted terminal repeat shows a deletion mutation. Regular PCR amplification cannot repair the sequence due to its repetitive nature. Azenta can successfully deliver repaired inverted terminal repeat regions through specific ITR correction technique.

IMPORTANCE OF INTACT ITR REGIONS IN AAV GENE THERAPY RESEARCH

Each inverted terminal repeat region is important in downstream AAV gene therapy applications*

Tech Note: An Efficient and Reliable Approach to AAV Packaging

Tech Note: An Efficient and Reliable Approach to AAV Packaging

 

While AAV is a powerful vehicle for gene delivery, unstable ITRs threaten the fidelity of rAAV genomes. Loss of ITR integrity diminishes the packaging efficiency of rAAV particles and thus viral titer. In this tech note, discover the effect of partial and full ITR deletions on AAV packaging and how to reliably identify and effectively correct them.

Tech Note: An Efficient and High-Fidelity Approach to AAV Plasmid Preparation

 

Azenta has recently developed a proprietary AAV plasmid preparation process, which significantly improves the chance of maintaining ITR integrity, even when other commercially available competent cells growing in low temperature have failed. This process can also isolate clones with full-length ITR from a sample mixture containing intact and truncated ITRs.
