Welcome to The Native Antigen Company

World leading infectious disease reagents from the experts

Whether you need cutting-edge reagents for your research or bulk products for manufacturing we can support your needs

Antigens, Antibodies, Immunoassays


We specialise in the development and manufacture of antigens, antibodies and immunoassays for viral and bacterial pathogens. We produce both native and recombinant antigens using our proprietary mammalian system and have decades of experience in bulk and scale production.

Custom and Contract Research Services


We can undertake custom projects to manufacture antigens and other proteins, prepare antibodies and develop immunoassays to support your R&D. Our development laboratories are fully staffed by a team of PhD molecular biologists and development scientists who are able to execute projects as short as a few days, through to long-term programmes of a year or more.

MXRA8 Receptor

Borrelia Antigens, Antibodies and Immunoassays

We now offer an extensive range of Borrelia burgdorferi antigens, antibodies and immunoassays. Our high-quality products are suitable for a range of laboratory research and vaccine development applications.

Zika Immunoassay Kit

Dengue and Zika eBooks

A major challenge faced by academic researchers, pharma and public health scientists is the close structural similarity between the Dengue and Zika viruses, which continues to hamper research efforts, requiring more sensitive diagnostic tools to differentiate between them. See our resources to download your free eBook and find out more.

Mammalian-Expressed Proteins

Using Adenoviruses to Fight Cancer

Adenoviruses are one of the major contenders for a new generation of oncolytic gene therapy vectors to treat cancer. In the second of a 2-part series, we discuss how adenoviruses are being developed as cancer therapeutics and some of the hurdles these platforms face from our own immune systems.

About The Native Antigen Company

The Native Antigen Company specialises in the development and manufacture of both native and recombinant antigens, antibodies and immunoassays for viruses and bacteria. Our antigens are used by leading pharmaceutical companies and IVD manufacturers in cutting-edge vaccine research and serology where proper folding and glycosylation are vital. As well as offering antigens from a rapidly expanding portfolio, we are increasing our range of highly specific antibodies and ELISA immunoassays. Our expertise is also available to customers on a contract basis for those needing custom protein manufacture in our proprietary mammalian cell protein expression system, together with antibody and immunoassay development.

Viral Lysates for Diagnostic Research

We've recently expanded our range of native viral cell lysates to complement our highly pure recombinant antigens. Here, we explain how our lysates are made and their uses in infectious disease R&D.What are viral lysates? Put simply, viral lysates are extracts of...

Cellular Receptors for Viral Entry

The most crucial step for viruses during human infection is recognition and entry into host cells. For this to happen, specific proteins on the virus capsid interact with those on the host cells' surface, through a 'lock-and-key'-type mechanism that mediates...

Using Adenoviruses to Fight Cancer

In the second of a 2-part series, we discuss how adenoviruses are being developed to treat cancer and some of the hurdles these platforms face from our own immune systems. Curing cancer is one of the biggest challenges of the 21st century. Our knowledge of cancer’s...

Repurposing Adenoviruses as Vectors for Vaccines

In the first of a 2-part series, we explore what makes adenoviruses so useful in gene therapy applications and how they are being developed as vectors for vaccines at the Jenner Institute in Oxford.   Adenoviruses (ADVs) are non-enveloped icosahedral DNA viruses...

New Immunofluorescence Data for our CMV, Yellow Fever and Ebola Antibodies

In September 2018 The Native Antigen Company and Virology Research Services (VRS) were awarded the Medical Research Council (Proximity to Discovery Award for Knowledge Exchange) to test a large panel of our viral antibodies in immunofluorescence applications. This...
