*Note: The tTA in this plasmid was made from a reverse tetracycline transactivator (rtTA) by changing two amino acids (G19E and P56A). These two residue changes have been shown to be sufficient for the reverse phenotype (10.1073/pnas.130192197).
Information for AAV1 (Catalog # 99120-AAV1) ( Back to top )

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.
