Viral Production & Use
- Packaging Plasmids encode adenoviral helper sequences and AAV rep gene, AAV1 cap gene
- Buffer PBS + 0.001% Pluronic F-68 + 200 mM NaCl
- Serotype AAV1
- Purification Iodixanol gradient ultracentrifugation
Requestor is responsible for compliance with their institution's biosafety regulations. Lentivirus is generally considered BSL-2. AAV is generally considered BSL-1, but may require BSL-2 handling depending on the insert. Biosafety Guide
Viral Quality Control
- Addgene ensures high quality viral vectors by optimizing and standardizing production protocols and performing rigorous quality control (QC) (see a list of our QC assays). The specific QC assays performed varies for each viral lot. To learn which specific QC assays were performed on your lot, please contact us.
- Titer: the exact titer of your sample will be reported on the tube. The titer you see listed on this page is the guaranteed minimum titer. See how titers are measured.
Visit our viral production page for more information.
Using FLEX vectors in vivo: LoxP sites in FLEX plasmids are known to recombine during DNA amplification and viral vector production, which may result in a minority of Cre-activated (i.e., "flipped") viral vectors. Addgene has measured this occurs in 0.1-0.6% of viral vectors in our typical production protocol. This can lead to a small number of cells exhibiting Cre-independent transgene expression in vivo. To address this, we recommend titrating to find the optimal AAV dosage required for Cre-dependent transgene expression and function in vivo. This may include reducing the viral vector dosage in order to reduce the likelihood of Cre-independent expression.
These plasmids were created by your colleagues. Please acknowledge the Principal Investigator, cite the article in which the plasmids were described, and include Addgene in the Materials and Methods of your future publications.
