Frequently Asked Questions (FAQs) for Plasmid and Viral Vector Products
-
Which serotype should I use?
Specificity is determined by the viral capsid proteins, so it is important to select the correct AAV serotype to ensure optimal gene delivery. The table below lists our recommended AAV serotypes for different target tissues. If you are unsure which AAV serotype will work best for your system, we recommend that you try out our AAV GFP Testing Kit. The testing kit contains the following viruses all driven by the strong CMV promoter: GFP AAV1, GFP AAV2, GFP AAV5, GFP AAV6, GFP AAV8, GFP AAV9, and GFP AAV-DJ.

Where can I find more information about biosensors?
For more information on biosensor gene therapy products, please visit the following Janelia pages about CaMPARI, GCaMP, jRCaMP1/jRGECO1, and iGluSnFR. You can also read our Biocompare article to learn why AAV biosensors are a powerful tool for tracking neuronal dynamics.
-
What are differences between the different GCaMP biosensors?
The number following GCaMP refers to the generation (3rd, 5th, 6th, or 7th). The letter at the end refers to the characteristics of the variant.
jGCaMP7s: sensitive and slow
jGCaMP7f: fast kinetics
jGCaMP7b: brighter baseline
jGCaMP7c: high contrastThe plasmids were generated by the Douglas Kim lab. For more information about the jGCaMP7 variants, please see their publication.

-
Are AAV products safe to use?
Yes, all of our AAV Parkinson’s disease tools are replication-incompetent and can be handled safely in a BSL-1 facility.
-
Are there any limitations to which ORFs can be shuttled?
If you want to generate viral particles, you must not exceed the packaging capacity of the virus. Please note that the packaging capacity refers to the total insert size between and including the ITRs or LTRs.
AAV cloning capacity: 4.7 kb
Adenovirus cloning capacity: 7.5 kb
Lentivirus cloning capacity: 6 kb -
How is ORF shuttled into a different vector?
The ORF cloned into the pENTER adenovirus shuttle vector can be transferred into the other Charles River’s destination vectors through a simple “cut and paste” restriction enzyme digestion and ligation. A combination of two pairs of restriction enzymes, AsiSI/MluI (96%), AsiSI/RsrII (99%) covers 99.5% of all human cDNA ORFs. All human genes can be covered with a few additional restriction enzyme combinations, such as AsiSI/NotI, AscI/RsrII.
-
When should I use plasmid versus virus for miRNA delivery?
Plasmid miRNA delivery may be sufficient for in vitro work or for conducting pilot studies. However, recombinant viruses are excellent tools for miRNA delivery both in vitro and in vivo. Adenovirus miRNAs in particular are a great choice if you need high transduction efficiency.
-
Does Charles River validate shRNA sequences?
We do not validate shRNA sequences designed as a part of the shRNA cloning services. However, we will send you the shRNA plasmids to test. Once you determine which shRNA construct works best for your experiments, we can package your selected shRNA construct into virus.
-
What promoters, reporters, and tags do you have available?
By default, expression of our lentivirus ORF cDNA clones are driven by the CMV promoter. C-terminal FLAG and Myc tags are included to allow for easy detection and purification of the overexpressed protein.
