The actual titer of each viral preparation is determined experimentally and will be reported with each shipment. Specific information on volume and titer can be seen on the material page for each viral item, but general guidelines are outlined below.
AAV Vectors
- We offer AAV vectors with titers ranging from 2 × 1012 – 3 × 1013 GC/mL. For ready-to-order AAV, there is a minimum guaranteed titer displayed for each vector, which will fall within that range and varies, for instance, based on serotype. The minimum is determined conservatively, based on our historical low among many production runs with that viral genomic plasmid. For a given lot, actual titers may be considerably higher than the advertised minimum guarantee.
Lentiviral Vectors (individual plasmids)
- We provide 1 mL of virus with titers of at least 105 TU/mL for viruses based on Cas9 plasmids, and 1 mL of at least 106 TU/mL for viruses based on most other plasmids.
Lentiviral Vectors (pooled libraries)
- We guarantee a total minimum particle count for each catalog item. The guaranteed particle amount is listed on each catalog item's page, and it will impact the total volume shipped. As a reference, we provide on the order of 13 mL of virus with titers of at least 107 TU/mL.
