PSEUDOVIRUS NEUTRALIZATION ASSAYS

The Pseudovirus Neutralization Assay is frequently used in virology since it is a useful tool for measuring the viral infection rate and hence, the effectiveness of antibodies or drugs that block the virus from entering cells. It has become a hot topic in SARS-CoV-2 research recently. Learn more about this method and about the instruments required to measure it.

Basic and Preclinical Research

In order to understand the mechanisms of infection and immunity required to control COVID-19, a broad range of technologies is needed.

Microplate Readers from Berthold Technologies are flexible instruments and suitable for many relevant methods, such as:

  • Luminescent reporter viruses, including Pseudovirus Neutralization Assays.
  • Interaction studies using BRET, FRET and TR-FRET.
  • ELISA of viral antigens or host antibodies.

Automated Systems from Berthold Technologies allow unattended automation of most microplate-based assays, such as:

  • ELISA of viral antigens or host antibodies.
  • Chemiluminescence- or fluorescence- based immunoassays.
  • Assessment of immune response using ELISpot.

Development of tests, drugs and vaccines

Development of vaccines, drugs and other therapeutic tools involves many different tasks, from immunogen characterization to evaluation of the immune response or screening of compounds, viral antigens or antibodies. Our microplate readers provide high flexibility and performance for all your detection needs. In addition, we provide automated all-in-one ELISA systems that allow you to walk away from your tedious immunoassays and concentrate on other important activities.

Such projects may also involve using cell-based assays for the screening of antibodies, antigens or compounds. This often requires washing and dispensing large quantities of cells growing in microplates. Our high-throughput microplate washers can be used for the gentle wash of adherent cells and, thanks to its built-in stacker, can wash batches of 30 plates, quickly and efficiently.

Microplate Washers

Manufacturing & QC

Once an ELISA test has been developed, tested and optimized, it is necessary to manufacture the kits to be deployed in laboratories around the globe. This requires the coating of microplates with the antigens or antibodies of interest, for example, SARS-CoV-2 antigens to make a serological test. Plate coating involves dispensing and washing large numbers of microplates.

The Zoom HT Plate Coating System is a high-throughput washer and dispenser which, thanks to its integrated stackers with single-rail design, can coat or block up to 250 plates/hour, and wash up to 150 plates/hour (3 washes/plate).

Quality Control is of utmost importance in any manufacturing process. The concentration of the product can be verified using absorbance, fluorescence or luminescence, which may be reliably measured using our microplate readers.

Testing

Many tests used to study the presence of antibodies against SARS-CoV-2 in blood are based on the ELISA principle. While performing an ELISA takes considerably more time than a rapid test, some ELISA tests are quantitative, and hence more informative.

Automated ELISA systems reduce hands-on time and human error when performing an ELISA. The Crocodile 5-in-one is a simple solution to automate ELISA in low-throughput laboratories.

For laboratories manually performing ELISA, the Apollo 11 is a reliable ELISA reader which uses a long-life LED light source.
