The V2 receptor is mainly found in the kidney and is important in free water reabsorption.\u003cbr\u003e\nThis HEK293 stable cell line expresses the V2 receptor fused to a SNAP-Tag. Labeled with Terbium, the cells can be used in a Tag-lite receptor binding protocol.\u003cbr\u003e\nTag-lite assays offer many features and applications over traditional receptor\/ligand binding assays:\u003c\/p\u003e\n\n\u003cp\u003eNon-radioactive\u003cbr\u003e\nHomogeneous and filtration-free\u003cbr\u003e\nReady-to-use kits and reagents for binding assays\u003cbr\u003e\nDoes not alter the receptor pharmacology\u003cbr\u003e\nPeer-reviewed, validated technology\u003cbr\u003e\nThorough kinetic studies with true Kd and Ki values, association (Kon) and dissociation (Koff) rate constants\u003cbr\u003e\nScreening and profiling of biologics and large molecules\u003cbr\u003e\nHow it works\u003cbr\u003e\nStep 1 - Receptor labeling\u003cbr\u003e\nSNAP-tag® is a small fusion tag that covalently interacts with specific substrates.

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.\u003c\/p\u003e\n\n\n\n\n  \u003cbr\u003e\n        \n\n\n\t\u003cbr\u003e\n  \u003cbr\u003e\n        \u003cbr\u003e\n  \n\n      \u003cbr\u003e\n  \u003cbr\u003e\n  \u003cbr\u003e\n    \u003cbr\u003e\n      \u003cbr\u003e\n        \u003cbr\u003e\n        \u003cbr\u003e\n        \u003cbr\u003e\n        \u003cbr\u003e\n      \u003cbr\u003e\n    \n\n    \u003cbr\u003e\n      \n\n      \u003cbr\u003e\n        \n\n      \u003cbr\u003e\n    \n\n  \n\n\n\n\n\n\n\u003cp\u003eStep 3 - Saturation binding (KD)\u003cbr\u003e\nA 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.\u003c\/p\u003e\n\n\n\n\n  \u003cbr\u003e\n        \n\n\n\t\u003cbr\u003e\n  \u003cbr\u003e\n        \u003cbr\u003e\n  \n\n      \u003cbr\u003e\n  \u003cbr\u003e\n  \u003cbr\u003e\n    \u003cbr\u003e\n      \u003cbr\u003e\n        \u003cbr\u003e\n        \u003cbr\u003e\n        \u003cbr\u003e\n        \u003cbr\u003e\n      \u003cbr\u003e\n    \n\n    \u003cbr\u003e\n      \n\n      \u003cbr\u003e\n        \n\n      \u003cbr\u003e\n    \n\n  \n\n\n\n\n\n\n\n\n  \u003cbr\u003e\n        \n\n\n\t\u003cbr\u003e\n  \u003cbr\u003e\n        \u003cbr\u003e\n  \n\n      \u003cbr\u003e\n  \u003cbr\u003e\n  \u003cbr\u003e\n    \u003cbr\u003e\n      \u003cbr\u003e\n        \u003cbr\u003e\n        \u003cbr\u003e\n        \u003cbr\u003e\n        \u003cbr\u003e\n      \u003cbr\u003e\n    \n\n    \u003cbr\u003e\n      \n\n      \u003cbr\u003e\n        \n\n      \u003cbr\u003e\n    \n\n  \n\n\n\n\n\n\n\u003cp\u003eStep 4 - Competitive binding (KI)\u003cbr\u003e\nA competitive binding assay is performed to measure the dissociation constant, Ki.
