PerkinElmer company EUROIMMUN has introduced SARS-CoV-2 NeutraLISA assay to determine the neutralising capacity of anti-SARS-CoV-2 antibodies.
Part of the firm’s portfolio of Covid-19 diagnostics, the CE-marked surrogate neutralisation test has been designed for the identification of neutralising antibodies against SARS-CoV-2.
The SARS-CoV-2 NeutraLISA will help determine the inhibitory effect of antibodies that can block the interaction between biochemically produced RBD and ACE2.
EUROIMMUN’s SARS-CoV-2 NeutraLISA assay, which is based on ELISA technology, uses non-pathogenic viral proteins.
The company has designed the assay to process in common lab settings either manually or automatically.
EUROIMMUN is currently offering SARS-CoV-2 NeutraLISA assay in more than 30 countries, which accept the CE mark.
EUROIMMUN CEO Dr Wolfgang Schlumberger said: “The SARS-CoV-2 NeutraLISA assay supplements EUROIMMUN’s existing CE-marked QuantiVac ELISA and SARS-CoV-2 Interferon-gamma Release Assay which is expected to be available with CE mark soon.
“In combination, the assays make a powerful trio to help evaluate the immune response to SARS-CoV-2 induced through natural infection or vaccination with S1/RBD-based vaccines from multiple angles.”
In December last year, EUROIMMUN secured CE mark approval for its new polymerase chain reaction (PCR) test to differentiate between Covid-19 and flu.
EUROIMMUN provides a range of Covid-19 products, including real-time PCR tests, an antigen detection assay for acute diagnostics, multiple antibody tests and a dried blood spot solution to help assess the immune response.
The company also offers the Interferon-gamma Release Assay for the assessment of specific T-cell response. It is currently available for research use only.
In addition, the company offers automation systems for small, medium and high sample throughput workflows.
