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.
Please note that this vector may have a higher level of recombination than our other FLEX vectors. We are making it available because it is still useful to some scientists, but understand that you may see expression in the absence of Cre.
Visit our viral production page for more information.
Addgene Comments
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 0.1-0.8% of viral particles in our typical production protocol. This can lead to a small number of cells exhibiting Cre-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 Cre-dependent transgene expression and function in vivo. This may include reducing the viral particle dosage in order to reduce the likelihood of Cre-independent expression.
Information for AAV Retrograde (Catalog # 104496-AAVrg) ( Back to top )
Purpose
Ready-to-use AAV Retrograde particles produced from pGP-AAV-CAG-FLEX-jGCaMP7f-WPRE (#104496). In addition to the viral particles, you will also receive purified pGP-AAV-CAG-FLEX-jGCaMP7f-WPRE plasmid DNA.
CAG-driven, Cre-dependent jGCaMP7f calcium sensor. These AAV were produced with a retrograde serotype, which permits retrograde access to projection neurons. These AAV preparations are suitable purity for injection into animals.Delivery

Addgene Comments
Retrograde functionality is dependent on high viral titers. Addgene recommends not diluting your AAV preps prior to use.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 0.1-0.8% of viral particles in our typical production protocol. This can lead to a small number of cells exhibiting Cre-independent transgene expression in vivo.
