Leaf Expression Systems Aids Research into the Novel Coronavirus (SARS-CoV-2, 2019-nCoV) with the Development of Recombinant SARS-CoV-2 N-Protein


NORWICH, UK – 17 June 2020: Leaf Expression Systems (Leaf), a contract development and manufacturing organisation based in Norwich, UK, has announced today that it has developed a recombinant SARS-CoV-2 N-protein (antigen) to aid research into the Novel Coronavirus (SARS-CoV-2, 2019-nCoV) pandemic.

The recombinant SARS-CoV-2 N-protein consists of the full-length Nucleocapsid protein (N-Protein) from SARS-Cov-2, appended with a His-Tag. The N-protein performs vital functions during the viral lifecycle of SARS-Cov-2; including binding and packaging of viral genomic RNA during replication and interacting with M-Protein (SARS-CoV-2 membrane protein) during viral assembly, making SARS-CoV-2 N-Protein a key research target for antiviral therapeutics and diagnostic testing.  The recombinant SARS-CoV-2 N-protein has been produced using the company’s proprietary transient expression technology, Hypertrans®, and can be used to further research potential solutions for the treatment and effective diagnosis of COVID-19 infections.

The N-Protein has further expanded Leaf’s growing product portfolio and it is available for purchase for research purposes via its online platform.

Simon Saxby, CEO said: ’We are pleased to be able to support the ongoing research into potential diagnostic and therapeutic solutions to combat the SARS-CoV-2 pandemic with the rapid production of the N-protein using Hypertrans®. This is further demonstration of the speed with which our plant-based transient expression technology can be used to produce diagnostic reagents or vaccines in response to sudden outbreaks of disease and support testing and immunization programmes.’

About Leaf Expression Systems
Leaf Expression Systems is a contract development and manufacturing business specialising in plant-based expression and production of proteins, vaccines and complex natural products for research and commercial applications. It uses Hypertrans®, the proprietary transient expression technology, which was originally developed by Professor George Lomonossoff of the John Innes Centre.

The Hypertrans® system allows for the rapid simultaneous production of multiple gene products in a controlled and coordinated manner within the tissues of plants. Using gene synthesis and modular vectors, new products such as vaccines, antibodies or enzymes can be produced at speed and on a large scale, so it is well suited to be able to rapidly respond to emergencies like pandemics.
