Article Citing this Plasmid
The addition of the P2A-nls-dTomato allows for easy identification of GCaMP6 expressing cells exhibiting nuclear red fluorescence that does not significantly overlap with the cytosolic GCaMP signal. The GCaMP and fluorophore are physically uncoupled.
Permissions were obtained from Douglas Kim and the Clontech licensing office for depositing this new plasmid.
Information for AAV Retrograde (Catalog # 51083-AAVrg) ( Back to top )
Ready-to-use AAV Retrograde particles produced from AAV-EF1a-DIO-GCaMP6f-P2A-nls-dTomato (#51083). In addition to the viral particles, you will also receive purified AAV-EF1a-DIO-GCaMP6f-P2A-nls-dTomato plasmid DNA.Cre-dependent GCaMP6f calcium sensor and physically separate nuclear tdTomato, under control of the EF1a promoter. 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 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.
