Vironova awarded a key US patent for further automation of transmission electron microscopy

Vironova is very happy to announce the granting of our US patent with the title " A method for automatic correction of astigmatism.” The method, which can be applied to any electron microscope, allows for automated correction of the electron beam, removing a tedious manual step that requires considerable operator skill. Ultimately it will enable fully automated image acquisition.

“This patent is a manifestation of our strategy to strengthen our core technology through a multi-disciplinary innovation process. Our constant goal is to increase user friendliness and improve the accessibility of the unique information inherent in electron microscopy." Says Mohammed Homman, CEO, Vironova

Webinar April 6 - Interview with Vironova founder and CEO Mohammed Homman

Vironova will host a webinar “Automated purity and integrity check of gene therapy vectors” on April 6 at 3 pm CET. (Agenda and registration can be found here.)

The webinar will demonstrate the capabilities of MiniTEM™ , which is compact, easy to use low-voltage transmission electron microscope system designed for nanoparticle characterization. It is pioneering in that its automatically acquired high-quality images reveal particle morphologies that can be transformed into accurate metrics

In conjunction with the above-mentioned webinar, the founder and CEO of Vironova Mohammed Homman shares his story of the company and MiniTEM. A journey that began with his own passion for viruses and treating viral diseases, and the limitations in available methods that led him to collaborate with a wide variety of specialists, and eventually building the MiniTEM system.

Vironova is building a state of the art electron microscopy (EM) facility to meet increasing demand

Vironova has established a growing number of global customers in the highly-regulated and quality demanding pharmaceutical industry, who focus on drug/gene delivery and vaccine development. Currently 7 of the 10 largest biopharmaceutical companies are clients to Vironova.

The new EM facility with a BSLII laboratory for sample preparation will greatly increase current capacity and meet the increasing demand for nanoparticle characterization services that the company provides. These are performed using TEM and the proprietary image analysis software VAS (Vironova Analyzer Software) in accordance with GMP, which is essential for applications in pharmaceutical development. Several Microscopists are being recruited for the new lab, which will be finalized during this year.

Vironova has filed a US provisional patent for analyzing viral vector content using cryoTEM

Vironova has now filed a patent for quantitative analysis of viral vector content using cryoTEM, a method that has already triggered plenty of interest amongst our customers.
In the pharmaceutical industry, viruses and virus-like particles are extensively used as carriers for gene delivery, so called viral vectors. Assessment of carrier particle content is of prime importance as it is directly linked to the efficacy of the treatment.

Negative stain TEM (nsTEM) is a standard approach for assessing this. Due to variations in staining and preparation the results are unreliable, whereas analysis using cryoTEM yields very consistent and reliable results. Vironova has now filed the patent for the quantitative analysis of viral vector content using cryoTEM.

Free webinar April 6: Automated purity and integrity analysis of gene therapy vectors

Time: 3:00pm London, 10:00am New York

Key learning objectives

  • How MiniTEM™ automatically images, detects and classifies viral particles in ~1h
  • How the proportion of intact vs broken Adeno-associated virus (AAV) and Adenovirus in different samples can be measured accurately
  • How to perform automated purity analysis of virus particle samples
A case study will be presented to demonstrate how the integrity and purity of AAV and Adenovirus particles can be measured automatically. Analysis is performed using MiniTEM, which enables automatic imaging, detection, classification and quantification of particles. As a result, a metric of the proportion of intact versus broken particles is presented.

Vironova AB signs one-year agreement with the U.S. Food and Drug Administration to beta test proprietary Vironova Analyzing Software (VAS).

In one of the fastest growing drug development areas today, nano-particles (for example liposomes), visible using electron microscopy, are used to deliver drugs to their exact targets in the body.

Proprietary Vironova Analyzing Software (VAS) in combination with Cryo-transmission electron microscopy (cryoTEM) enables semi-automated image analysis of liposomes, providing accurate, reproducible and timely results.

“Beta-testing is designed to help us accelerate development and improve the robustness and user friendliness of VAS. This is a very valuable compliment to the input from our internal microscopists who work with liposome characterization,” says Nina Ewerlöf, Head of Vironova instruments and software.

The U.S. Food and Drug Administration's National Center for Toxicological Research is a global resource for innovative scientific solutions in support of the agency’s mission to improve public health.
