January 2017: Innovate UK Grant
The Native Antigen Company has won a grant from Innovate UK to produce a new range of antigens for research into the Dengue virus. The company is at the stage of expanding its research expertise to produce antigens for emerging markets which are more challenging to manufacture and have a high impact of improving healthcare. One example of this is Dengue Fever, an infectious tropical disease caused by the Dengue virus. Unless detected early and controlled, the disease may manifest into the life-threatening dengue hemorrhagic fever (DHF). DHF is now endemic in more than 110 countries and severe forms of the disease carry a mortality of up to 26%. Producing a suitable antigen will, for the first time, offer a simple and cost-effective means of accurately detecting DHF at the community level. The project will exemplify a new platform opportunity for the company and enable us to address other pathogens in the future. Read more.

The Native Antigen Company was formed as a spin out from PsiOxus (formerly Hybrid BioSystems). Headquartered in Birmingham, with research offices in Oxford, The Native Antigen Company has expertise in the isolation and purification of both viral and bacterial native antigens. These antigens serve as key components for infectious disease testing kits – their function being to accurately detect pathogenic infection by capturing antibodies in patient samples
The company also offers adenovirus purification and production capabilities and a screening service for anticancer and antiviral drug compounds. The company has achieved ISO 9001:2008 accreditation for the development, manufacture, and sale of native antigens as of November 2010. The company will specialise in manufacturing of native antigens but also offers a range of products and purities, from cell lysates to gradient purified pathogens, for a range of organisms. These include adenovirus types 3, 5, 11, 12, and type 5 hexon protein along with astrovirus type 1, Chlamydia trachomatis, HSV types 1 and 2, Neisseria gonorrhea, and Trichomonas vaginalis. Mycoplasma pneumonia products are in development.
“Most antigens used in current diagnostic kits are not native and can thus lack the specificity and sensitivity which we offer with our native antigens,” says Andrew Mawell (CEO). “Industry has become reliant on recombinant antigens in part due to perceived cost savings and ease of manufacture. There is a clear gap for an innovative company that can focus its expertise in the isolation and purification of native antigens and is prepared to work closely with the kit manufacturers to provide tailored, cost-effective solutions.” Read more.
