emphasis is also given to the importance of methodological advances in receptor isolation , immunologic analysis of receptor structure and function , the development of new instrumentation for microchemical characterization of very small amounts of receptor material , and the increasing use of genetic engineering techniques to isolate the genes for receptors and their regulatory subunits , to transfer such genes between cells , and to study receptor function by creating structurally modified receptors via subtle changes in gene structure .
