Overview
Tag-lite receptor binding assays use either a green or a red fluorescent ligand to function.
This CXCR4 receptor red agonist is a SDF1 alpha derivative labeled with a red emitting HTRF fluorescent probe.
This ligand is best suited for use in the Chemokine CXCR4 receptor binding assay.
Benefits
- FLUORESCENTLY LABELED LIGAND
- HIGHLY STABLE
- VALIDATED IN BINDING
Assay principle
Running a receptor binding assay using Tag-lite is as easy as it can get. 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.
