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 recombinase-dependent vectors in vivo: FRT sites in fDIO plasmids are known to recombine during DNA amplification and viral vector production, which may result in a minority of Flp-activated (i.e., "flipped") viral vectors. Addgene has measured this occurs in 0.1-0.8% of viral particles in our typical production protocol. This can lead to a small number of cells exhibiting Flp-independent transgene expression in vivo. To address this, it is necessary to optimize the injection volume and viral titer to find the optimal AAV dosage required for Flp-dependent transgene expression and function in vivo. This may include reducing the viral particle dosage in order to reduce the likelihood of Flp-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.
