- GC = Genome copies.
- For these extremely low-yield AAV serotypes without production data, we are not able to guarantee the final yield or titer specified here.
- If you would like to use any AAV serotypes that are currently under patent, and your application is for commercial use, we advise that you contact the patent owner to obtain authorization beforehand.
Storage Requirements:
- Store the virus at -80°C, and place it on ice during operation.
- Calculate your expected usage in advance and PackGene will aliquot your virus according to your pre-determined requirements. This can help avoid unnecessary thawing and re-freezing after receiving your AAVs since freeze thaw cycles influence virus viability. If aliquoting is required, it is recommended to use PCR tubes with siliconized inner walls, or special virus preservation tubes with low protein binding rates.
- Thaw your virus aliquots in an ice bath immediately before use.
- Dilute with PBS or PBS / 0.001% F-68 if needed.
Quality Control
A variety of AAV-based QC assays have been developed by PackGene’s experienced QC team. QC tests are aimed at verification of the identity, purity, and potency of AAV viral particles for both in vitro and in vivo studies. AAV genome copies are quantified via SYBR qPCR with ATCC’s Reference AAV for titer calibration. Purity is determined by Coomassie-Blue staining.
We guarantee the endotoxin level of the AAV particles lower than 10 EU/ml. We also offer additional QC tests including ddPCR , TEM, TCID50 tittering and other QC services. Please check AAV Analytical Services to learn more.
