Overview

One of four adenosine receptors found in the brain, A2A is a GPCR. A2A receptor is thought to play a role in acute and chronic neurodegenerative disorders such as cerebral ischemia or Parkinson's disease. A2A may also be involved in seizures and sleep disorders.

Cells expressing the A2A 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 A2A 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.

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.

Kd and Ki validation

Examples of data obtained using A2A labeled cells and their matching fluorescent ligand (L0058RED). ZM-241385 was used as reference ligand. Results may vary from one HTRF® compatible reader to another.
