Reliable AAV Capsid Titer determination
Recombinant Adeno-Associated Virus (rAAV) vectors are increasingly used for in vivo gene transfer to target inherited genetic diseases. Yet it is essential to carry out a reliable quantification of rAAV capsid titers to ensure a safe gene transfer to the target cell.
As the industry gold standard you can rely on PROGEN’s AAV ELISAs to consistently deliver dependable capsid titer determination. You can select from a portfolio of AAV titration ELISAs and Xpress ELISAs for the most commonly used AAV serotypes. These are based on PROGEN‘s exclusive portfolio of AAV particle antibodies.
Your AAV ELISA Benefits
Easy-to-use: all assays use a similar workflow for all AAV serotypes and do not require expensive equipment or special training. Includes single-break strips that can be used separately for different test runs.
Quick: the ELISA Kits are ready to be shipped and easy to implement into all workflows. The Xpress ELISA Kits generate results in less than 2 hours without compromising performance.
Reliable: PROGEN‘s exclusive particle antibodies recognize native, non-denatured AAV capsids (full and empty) for the quantification of intact AAV particles. An industry gold standard with established success in clinical trials.
Reproducible: an established and robust method that generates reproducible data (See Figure 1). Regular AAV ELISA users can easily achieve low inter- & intra-assay variance with a coefficient of variation (CV) below 10%.
Accurate: AAV2 and AAV8 ELISAs are based on the ATCC international reference standard material and all remaining ELISAs (AAV1, 3, 5, 6, 9 and rh10) adhere to internal gold standards.
GMP-ready: can be validated for use in a GMP setting and adhere to FDA guidelines for the development of AAV gene therapies.

AAV Xpress ELISAs
Results in less than 2 hours
AAV Xpress ELISAs were created in response to the increasing need industry wide to get results faster and save time. The kit components have been adjusted to reduce the assay time by more than 50%. The Xpress ELISA kits have been developed based on the standard PROGEN ELISA kits, so they show the same accuracy and reproducibility. The only difference is you will be able to process a higher number of samples in less time.
Both PROGEN's AAV ELISA and AAV ELISA Xpress Kits have reference standard status in gene therapy centers worldwide.
What customers are saying
We’ve been using several kits every week and have had no trouble at all with them. We’ve been getting very good reproducibility and low variability between repeats, assays and users. Everyone is enjoying the speed of the assay and it has increased our throughput too.

PROGEN’s ELISA kits were easily transferable to our Dynex DS2 automated ELISA system. Measuring viral particle titers through an automated ELISA system instead of doing it manually, frees up a lot of time.
