About us: IAI AG

The Institute for Applied Immunology IAI AG was founded in Horgen in 1986. At the beginning, the focus of activity was on serum production.

When the biologist Dr. Herrmann Wolf took over the management of the company in 1993, there was a simultaneous shift in the focus of activities toward molecular biology and a specialization in dental topics. Products such as genotyping and various biodiversity studies established the basis for IAI AG's successful corporate development. On this basis, the first microbiological detection method for periodontitis diagnostics, the iai PadoTest 4-5, was developed and launched on the market to great response.

The iai PadoTest 4-5 quickly advanced to become the leading product of the Institute for Applied Immunology and, with its history, represents the longest-established diagnostic on the market for the detection of periodontitis marker germs.

In addition to developing new diagnostic methods, IAI AG collaborates with universities in Switzerland and Germany as well as numerous scientific research institutions. The integration of the latest technologies (e.g. Next Generation Sequencing) into competitive products plays a major role in the area of research and development.


In addition, IAI AG is involved in ongoing studies through collaborations that serve to improve and further develop existing products.


Since 2005, the headquarters of IAI AG is located in Zuchwil/SO.
