PRISM is a good package which we use for EC50 calculations and enzyme
kinetics. You might also try ORIGIN http://www.microcal.com/ . If you want
something that uses Excel you could consider XLFIT from IDBS
http://www.idbs.co.uk/ which is part of a corporate database system but can
be used stand alone,
