Validated Pseudoviruses

Influenza, SARS-CoV-2, Ebola, RSV and other surrogate viruses for neutralization assays and antibody discovery

Pseudovirus viral vector production for neutralization assays using our manufacturing processes

Our advantages

IVANO Bioscience offers validated pseudoviruses enabling scientists to perform functional assays such as virus neutralization tests in a BSL-2 laboratory. Whether you develop vaccines or antiviral drugs (e.g. monoclonal antibodies), our production platform was optimized to provide you with scalable volumes of pseudoviruses and hence, support you from research to clinical development.

Functional validation report

The quality of each production batch is verified through an infection efficiency and a neutralization assay. Additional validation assays can be done on demand.

Large scale production capability

Get reproducible and consistent results along your project by using the same production batch.

Pseudotype customization

We offer a streamline pseudovirus customization service, allowing you to focus on the development of your solutions against infectious diseases.

Efficient and affordable

We provide you only with freshly produced, highly efficient and concentrated pseudoviruses. For several of our pseudoviruses, you need to use only 1 µL/reaction.

Pseudovirus library

Our catalog is scalable according to your needs. Below, you will find our pseudovirus list for which the production process has already been optimized by our expert team.

Capacity: 1 000 reactions/mL or 10 plates/mL following our lab conditions in 96-well plates with luciferase detection.

Volumes: 1 mL, 5 mL, 10 mL and 20 mL of concentrated pseudoviruses. Larger volumes on demand.

Reporter genes: Firefly luciferase or GFP. Other on demand.

Custom production

Our expert team composed of Ph.Ds. and bioengineers, combines 20 years of experiences in manufacturing viral vectors, virus-like particles, and recombinant proteins. IVANO’s team has acquired its know-how through several collaborations with the National Research Council of Canada, a center of excellence in biomanufacturing, resulting in several publications [1] [2] [3] [4] [5].

Our custom production service merges valuable expertise with the commitment to making pseudoviruses accessible to every scientist. Whether you need a surrogate virus for influenza, RSV, SARS-CoV-2, Nipah, Rift Valley Fever, Ebola, Zika, Lassa, or Chikungunya, our team has numerous bioproduction tricks up its sleeves to provide you with unique pseudoviruses.
