AAV Plasmid Preparation


Preserving the integrity of inverted terminal repeat (ITR) sequences in adeno-associated virus (AAV) plasmids is important for the production of recombinant AAV (rAAV) vectors. GENEWIZ’s proprietary AAV plasmid preparation service delivers superior quality for midi to giga-scale AAV vectors, while maintaining the integrity of ITR regions. Our new process includes pre- and post-preparation quality controlled (QC) steps that leverage GENEWIZ's AAV-ITR Sanger sequencing capabilities for full sequence verification and ensures delivery of intact ITR clones for your research.

*Plasmid DNA is currently the only starting material accepted

Note: Screening and selection of intact ITR clones incurs additional cost

Features & Benefits

Turnaround time starting at 6 business days** with Ph.D.-level support throughout project.

High-quality midi- to giga-scale preps available.

High success rate compared to standard plasmid preparation kits and protocols.

Multiple analysis options available, including sterility testing, restriction digest, full plasmid sequencing, etc.

Screening process to isolate intact ITRs in mixed populations.

**6-day turnaround time for samples that have previously been ITR sequence verified at GENEWIZ.




AAV Plasmid Preparation Technical Information


GENEWIZ 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.

AAV-ITR Sequencing Tech Note


GENEWIZ has developed a high-quality, direct Sanger sequencing method that reads through both intact and commonly mutated inverted terminal repeat (ITR) regions of adeno-associated virus (AAV). This method is an effective tool for assessing the integrity of ITRs in AAV plasmids.


*Samples must arrive at the GENEWIZ New Jersey laboratory before 10:00 am EST to qualify for Same Day service. Note that
direct-sequencing templates are not available for our Same Day service.
