G-Protein-Coupled Receptor Microarrays

摘要

Membrane-bound proteins represent the single most important class of drug targets. Arraying these proteins is difficult because they typically need to be embedded in membranes to maintain their correctly folded conformations. We describe here the fabrication of microarrays consisting of G-protein-coupled receptors (GPCRs)—the single largest family of membrane-bound proteins—by robotic pin-printing on slides, and demonstrate assays for screening of ligands on these arrays.
