Our naming designation refers to the structural Rep proteins from AAV2 followed by the capsid serotype, for example AAV2/5. 

AAV vectors are offered in the following serotypes: AAV2/1, AAV2/2,  AAV2/5, AAV2/6, AAV2/6.2, AAV2/8, AAV2/9, AAV2/DJ, AAV2/rh10, PHP.B, PHP.eB, PHP.S.  

Vectors are provided in F68/PBS.  F68/PBS storage buffer does not require dialysis and is biocompatible with 0.001% Lutrol/F68 (poloxamer 188) to prevent aggregation of virus.

Triple Transfection System- $2,600

The vectors are prepared by a triple plasmid transfection in HEK-293 cells. The cis-acting AAV plasmid carries the AAV expression cassette containing the gene of interest flanked by the AAV2 inverted terminal repeats (ITRs). A second plasmid provides the genes for the structural proteins, rep and cap. The third pHelper plasmid provides the adenovirus helper genes. The triple transfection system works with any AAV plasmid from any source. 

Material provided: 500 µl in 100 µl aliquots (Titer: 5x10¹¹ to 1x10¹³ vg/ml (viral genomes/ml). Additional aliquots may be ordered with a minimum order of 500ul.

Serotypes: AAV2/1, AAV2/2, AAV2/5, AAV2/6, AAV2/6.2, AAV2/8, AAV2/9, AAV2/DJ, AAV2/rh10, PHP.B, PHP.eB, and PHP.S. Modified capsids are considered on a case by case basis. 

Shuttle: A cloning/expression AAV shuttle vector is provided after a Material Transfer Agreement is signed. Other outside pAAV shuttle vectors are also compatible with this system.

Sample required: 1500 µg of high-quality, transfection-grade AAV plasmid expressing the gene of interest at a concentration greater than 0.50 µg/µl with an A260/280 ratio of at least 1.80.

Sample Plasmid Quality Control: We require full plasmid sequencing. Every time an AAV shuttle plasmid is amplified, recombination can occur with the Inverted Terminal Repeats (ITRs) of the plasmid preventing the cassette from being packaged into virus. There are several companies that do this rapidly in a cost-effective manner. Some of these companies have a dropbox available on many US campuses.

Suggested additional Plasmid Quality Control:  Prior to sending sample for sequencing, we suggest digests to look for integrity within the ITRs. Please load a sample of at least 300ng of the DNA per well to get the best results. Suggested digests as follows: 

1. Lane 1 : Clearly Labeled Molecular Weight Ladder
2. Lane 2 : Uncut 
3. Lane 3 :  BssHII single digest 
4. Lane 4 : MscI single digest
5. Lane 5 : XmaI or SmaI single digest

Timeline: 3-4 weeks from the time the plasmid is received depending on the current queue and serotype.

Services include:

• Transfection.
• Large-scale amplification of AAV vectors.
• Purification performed using a variety of methods depending on the serotype. Most often this is an iodixanol gradient, followed by either an ion-exchange filter membrane or affinity chromatography. CsCl purification is also commonly used.
• Quality control assays include a physical titer (vg/ml) by ddPCR, transduced titer by FACS when appropriate, and silver stain to further assess virus titer and purity.
• Vehicle: The vectors are provided in F68/PBS

Sample Quality Screening and Disclaimer

Every effort is made to deliver a high titer, high quality viral vector. Viral vector preps are repeated a second time if they do not pass our quality control at no charge, provided that the plasmid submitted meets several criteria. We require gene information, a sequence, map, and ITR digest upon submission of a new project.

Preps will not be repeated and charges will apply to the first prep regardless of outcome in the following situations:

• Constructs that are over packaging capacity. This is ~4.7 kb from ITR to ITR for single stranded AAV and ~2.2 kb from ITR to ITR for self-complementary AAV.
• Where the shuttle backbone size is equal to or smaller than the ITR to ITR transgene. 
• Involve a novel or modified capsid.
• Constructs where the sequence does not match the ITR digest. We highly suggest that you perform your own ITR digest before submission of a project. This is especially important on plasmids you may obtain from another lab. 

Investigators will be notified when constructs are flagged as problematic and we will discuss the pros, cons, and finances of proceeding with the project. Sometimes the gamble to proceed with plasmids that fall under these criteria are warranted and we will do our best to guide you in the decision process.

Despite best efforts, some genes of interest may confer cellular toxicity that results in lower vector titers. We will notify investigators of progress and problems and discuss the next step if problems are noted.
