Over past few years, SNAP-Tag technology combined with TR-FRET has paved way development of many non-radioactive, no-wash, binding assays. method is based on transfecting cells using plasmids encoding a SNAP-Tag and subsequently labeling m with Terbium. Revvity offers a large collection of such plasmids. All GPCR genes are cloned in an expression vector directly downstream from a CMV promoter, and are provided ready protein expression and labeling.
All information on this page pertains to Tag-lite plasmid cloned with Beta2 adreno receptor.
Tag-lite assays offer many features and applications over traditional receptor/ligand binding assays:
- Non-radioactive
- Homogeneous and filtration-free
- Ready-to-use kits and reagents for binding assays
- Does not alter the receptor pharmacology
- Peer-reviewed, validated technology
- Thorough kinetic studies with true Kd and Ki values, association (Kon) and dissociation (Koff) rate constants
- Screening and profiling of biologics and large molecules
