The design and analysis of biological assays of mixtures


The simultaneous activity of multiple stimuli can be difficult to analyze, particularly on biological systems. However, these analyses are becoming increasingly important in drug or pesticide formulation for efficacy and in understanding the impact of environmental contaminants on ecological systems. This presentation will review techniques for the design and analysis of bioassays of mixtures. The two major techniques that will be reviewed are based upon the concepts of response and potency. Particular emphasis will be placed upon measuring levels of synergy, i.e., when the activity is greater than the sum of its parts, and antagonism, i.e., when the activity is less than would be expected. Theoretical examples will be given to demonstrate the application of each technique.

Bio of Speaker:

A biostatistician for DuPont Crop Protection at the Stine-Haskell Research Center in Newark, Dr. Stanley received his doctorate from Cornell University, where he studied the application of probabilistic modeling to integrated insect pest management. Over his career at DuPont, he has worked as a research biologist, ecotoxicologist and statistician. Currently, he is the Biostatistics Group Leader for new product discovery and development.
