Our history

In the mid 1960’s, three scientists – Leif Wide, Rolf Axén and Jerker Porath – convinced Pharmacia’s management to collaborate with them on the commercial development of Pharmacia’s separation medium, Sephadex, as the solid phase in immunodiagnostic testing. This was the first step towards the development of ImmunoDiagnostics.

Simultaneously, immunoglobulin E (or IgE) was discovered by two separate research teams, one in the USA, and one at Uppsala University Hospital (S.G.O. Johansson, Hans Bennich and Leif Wide). At Uppsala University Hospital, the team developed a method to measure the levels of the substance in blood samples and, eventually, a connection was made between IgE antibodies and allergic symptoms. These findings were presented to Pharmacia with the intent of creating a commercial allergy test. With the help of the Sandwich technology, developed by Leif Wide, the product Phadebas RAST was established and, with it, the leading position that ImmunoDiagnostics still holds in allergy testing.

The following is a short summary of the journey from a small R&D group within Pharmacia to the independent, world-leading company that it is today.
