ABSTRACT:
The present invention provides a general approach for G protein coupled receptors that may be used to define agonists and antagonists, and the specificity of receptor coupling to G protein subunits. Methods of the present invention use small volumes (microliters) and are compatible with high throughput flow cytometry. When assays of the present invention are multiplexed, the specificity of the interactions of a receptor with many G proteins may be determined simultaneously.
