Welcome to AFFINITY 2005

It is a great pleasure to welcome you to Uppsala and the 16’th Affi nity Conference. Uppsala hosts northern Europe ́s oldest university, the workplace for luminaries such as Linnaeus, Celsius, and Arrhenius, and this has been the site of path-breaking developments in protein separation from the early 1920’s to the present. Well known are Profs. The Svedberg (the ultracentifuge), Arne Tiselius (electrophoresis and chromatography), and Jerker Porath (gel fi ltration, affi nity chromatography and IMAC). Thus Uppsala seems to be a most appropriate place to discuss and share new breakthroughs in affi nity related interaction phenomena and their applications.
