Overview
Dopaminergic neurons and dopamine receptors are the most numerous in brain. In the brain, dopamine receptors D1 and D2 are GPCR responsible for such crucial processes as voluntary movement, sleep, regulation of food intake, attention, learning, and working memory.
Cells expressing the D2 receptor are provided pre-labeled with Terbium, and can be used to conduct receptor binding studies on the aforementioned receptor.
Benefits
- PRE-LABELED WITH TERBIUM
- FROZEN CELLS, READY TO BE USED
- CELLS/LIGAND VALIDATED FOR BINDING
Assay principle
Running your D2 receptor binding assay using Tag-lite is as easy as it can gets. Simply dispense 10 µL of labeled cells into each well, followed by 5 µL of labeled ligand and 5 µL of the compound you wish to test. Like all HTRF assays, Tag-lite assays do not require any washing steps. A diagram of the procedure to be followed is given on the right.
Saturation binding (KD)
A saturation binding assay measures total and non-specific binding for increasing concentrations of ligand under equilibrium conditions. To perform the assay, the fluorescent ligand is titrated into a solution containing a fixed amount of labeled cells and then incubated to equilibrium. The HTRF ratio obtained from this titration is the total binding.
Watch this video explaining how to run a saturation binding assay using Tag-lite.
Competitive binding (KI)
A competitive binding assay is performed to measure the dissociation constant, Ki. To perform the assay, the compound is titrated into a solution containing a fixed concentration of fluorescent ligand and a fixed amount of cells.
Watch this video explaining how to run a competitive binding assay using Tag-lite.
Kd and Ki validation
Examples of data obtained using Dopamine D2 labeled cells and their matching fluorescent ligand (L0002RED). Bromocriptine was used as reference ligand. Results may vary from one HTRF® compatible reader to another.
