Label-Free Receptor Assays.
نویسنده
چکیده
Label-free biosensors offer integrated, kinetic and multi-parametric measures of receptor biology and ligand pharmacology in whole cells. Being highly sensitive and pathway-unbiased, label-free receptor assays can be used to probe the systems cell biology including pleiotropic signaling of receptors, and to characterize the functional selectivity and phenotypic pharmacology of ligand molecules. These assays provide a new dimension for elucidating receptor biology and for facilitating drug discovery.

متن کاملA Comparative Study of Impedance versus Optical Label-Free Systems Relative to Labelled Assays in a Predominantly Gi Coupled GPCR (C5aR) Signalling
Profiling ligand function on G-protein coupled receptors (GPCRs) typically involves using transfected cells over-expressing a target of interest, a labelled ligand, and intracellular secondary messenger reporters. In contrast, label-free assays are sensitive enough to allow detection in native cells, which may provide a more physiologically relevant readout. Here, we compare four agonists (nati...
متن کاملSensitive protein:ligand biochemical assays using Corning® Epic® label-free technology on the EnSpire Multimode Plate Reader
While antibody-based fluorescence and radioactive detection technologies have dominated drug discovery and biological research worldwide, label-free technology is becoming widely accepted as a valuable research tool for mechanism-of-action (MOA) studies in lead optimization and receptor pharmacology. Here we introduce EnSpire® Multimode Plate Reader with Corning® Epic® label-free technology. Th...
متن کاملLabel-free integrative pharmacology on-target of drugs at the β2-adrenergic receptor
We describe a label-free integrative pharmacology on-target (iPOT) method to assess the pharmacology of drugs at the β(2)-adrenergic receptor. This method combines dynamic mass redistribution (DMR) assays using an array of probe molecule-hijacked cells with similarity analysis. The whole cell DMR assays track cell system-based, ligand-directed, and kinetics-dependent biased activities of the dr...
