Next generation technology for virus/viral vector imaging applied in antiviral screening, gene delivery and oncolytic virotherapies
NeoVirTech has developed a breakthrough technology to directly visualize and quantify in real time virus/viral vector infection and replication in living cells. NeoVirTech possesses the exclusive worldwide license for the ANCHORTM technology, a new generation of autofluorescent system allowing the visualization of viral DNA in living cells.
The ANCHOR system is composed of two parts:
- The ANCH sequence: short (from 200NT to 1kb) and unique (non repetitive), the sequence contains nucleation seeds for the binding of OR proteins. Insertion of the sequence in the viral genome does not perturb DNA metabolism or virus production.
- The OR-fluorescent protein expressing gene which specifically recognizes and spreads on the ANCH sequence, triggering the formation of a fluorescent focus easily detectable and quantifiable by microscopy (either classical or High Content). The strong accumulation of OR-FP protein onto its cognate ANCH sequence (up to 500 OR-FP/ANCH) is far enough to detect single DNA molecules. Therefore, fluorescent spot corresponds to the position of a single viral DNA copy.
The ANCH sequence is cloned upstream of the Or-FP expressing gene and inserted directly inside the DNA of interest (plasmid, gene, transposon, virus, viral vector used in gene therapy or oncolytic products). This autonomous ANCHOR cassette will convert target DNA into an autofluorescent molecule. NeoVirTech can use up to four different ANCHOR systems, with different length and fused to their corresponding fluorescent proteins, that can be used in combinations to detect several class of DNA simultaneously. Using the ANCHORTM technology, fitness studies visualizing co-infection of several viruses in real time are now possible.

We are developing inhibitors of intracellular trafficking pathways that block virus entry into cells. NeoVirTech’s technology allows for precise ranking of sets of analogues according to their antiviral potencies and selectivity indexes.
Working with NeoVirTech was a great experience. Preparatory discussions were rich and efficient, adaptation of protocols to our needs was very successful, antiviral screening of our molecules was done rapidly, and activity reports were clear and informative. The team was always available to answer our questions. We warmly recommend NeoVirTech for the screening and potency assessment of antiviral molecules on designated viruses.

The Technology Transfer Office Aquitaine Science Transfert (AST) aims to accelerate the dissemination of innovations on the market. AST supports innovative concepts from the researcher’s invention until proof-of-concept has been established. For a project of our portfolio, we were looking for a partner to evaluate the antiviral activity of a patented compound on infection and replication of different virus families. We had efficient and productive interactions with Dr Franck Gallardo and his team throughout the project to design the study, plan the execution and discuss about the results. I would highly recommend Neovirtech for antiviral drug evaluation.

Transgene SA is a biopharmaceutical company developing for more than 30 years innovative targeted-immunotherapies to answer unmet medical needs in the oncology and infectious disease fields. We were looking for a rapid and efficient solution to investigate the behavior of our products using high-resolution quantitative microscopy. NeoVirTech’s autofluorescence technology and screening platform allowed us to precisely visualize, understand and compare the behavior of our products directly using live cell microscopy techniques. The beauty and quality of the data they can generate open a new perspective for our activities, boosting up our research and validation processes. Thank you NeoVirTech for this ongoing precious collaboration.

For almost 40 years, InvivoGen had developed and commercialized several hundreds of compounds for innate immunity field. We are interested in testing the activity of some new proprietary compounds in the anti-infectious domain. NeoVirTech was a ‘local’ choice for this project. The technology they proposed combined quantitative and qualitative results in a high throughput screening format. Their expertise in virology, the speed and quality of the generated data led us to rapidly identify new compounds as antiviral.

Advances in immune suppression allows the grafting of life saving cells and organs between patients. Immune suppression unfortunately also promotes viral infections normally controlled by the immune system making the development of novel antivirals that work under immune suppression an imperative task. The underlying mechanisms causing reactivation or promoting viral replication are often related to dynamic changes in the chromatin status of the viral genome. Working with NeoVirtech gives us the unique opportunity to label viral genomes with the ANCHOR technology and study the dynamic behaviour of individual viral genomes in living cells under different environmental conditions. Understanding how viral genomes respond in living cells is key to understanding and developing novel drug concepts and mechanistic understanding of existing antivirals. Setting up the technology with NeoVirtech was simple, professional and driven by scientific understanding … the start of a great ongoing relationship!

Viral diseases cause significant financial loss in animal production systems. Despite the importance of viral pathogens as primary and secondary etiologic agents in cattle, pigs and poultry, no antiviral products are commercially licensed for use in veterinary medicine. Collaboration with NeoVirTech give us unique opportunity to explore the potential of antiviral therapy in the veterinary virology domain. Among viral animal diseases, we are particularly interested in poxviruses induced diseases of rabbit and poultry (myxomatosis, fowlpox), and labelling of DNA viral genomes with the ANCHOR technology will allow us to rapidly screen available compounds for antiviral significative effects.
