Recombinant antigens for IVD of infectious diseases

Rekom Biotech offers a wide range of recombinant antigens for in vitro diagnosis of human and animal infectious diseases, including those of zoonotic origin. These antigens will allow you to manufacture your antibody tests with a validated raw material of high quality and reproducibility, viable for any existing diagnostic platform on the market. You can also use them as internal control for an antigen test, and as immunogen to obtain antibodies. Given our extensive experience in the sector, we can advise you on what best suits your project. Trust us!

We design and produce recombinant antigens for IVD infectious diseases in the areas of bacteriology, mycology, parasitology and virology. Take a look at our portfolio!
