Thanks Lar! - I have always had fun trying to match drug effects to receptor binding affinities. This will make it much easier. The papers that I have all seem to contain the occasional conflicting value. I was preparing a lecture once and that just drove me crazy.

The internet is really starting to become a useful tool. There are some really intelligent people out there that are willing to share the life's work without slapping a patent on it and charging throught he nose for the priviledge using their information. It is the availability of information of this quality that almost restores my faith in humanity (that is, if I believed in the concept of "faith"). Thanks again - Cam
