Abstract
The increasing accessibility of genetically engineered receptor systems for the study of drug-receptor interaction has led to a corresponding increase in the testing of new drug entities in recombinant receptor systems. In this article Terry Kenakin illustrates some possible conditions within these recombinant systems where the relative stoichiometry of the receptors to other cellular components may differ from that found in natural systems and where this difference may lead to anomalies in drug testing.
