Information for AAV Retrograde (Catalog # 154867-AAVrg) ( Back to top )
Ready-to-use AAV Retrograde particles produced from pAAV-hSyn-fDIO-hM4D(Gi)-mCherry-WPREpA (#154867). In addition to the viral particles, you will also receive purified pAAV-hSyn-fDIO-hM4D(Gi)-mCherry-WPREpA plasmid DNA.Syn-driven, Flp-dependent hM4D(Gi) receptor with an mCherry reporter for CNO-induced neuronal inhibition. 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.

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.
Addgene CommentsRetrograde functionality is dependent on high viral titers. Addgene recommends not diluting your AAV preps prior to use.
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.
