The binding assay starter pack consists of three references, the labeled cells, the fluorescent ligand and the Tag-lite buffer. Each component must be ordered separately. The cells express the SNAP-receptor labeled with terbium cryptate (labeling performed with Tag-lite SNAP-Lumi4 Tb). The labeled cells are proposed in a 1 million cell pack, to achieve a minimum of 100 tests at a cell density of 10,000 cells/well.
- Tag-lite Bombesin receptors red agonist is a Bombesin derivative labeled with a red emitting HTRF fluorescent probe
- This ligand has been successfully used in a Bombesin BB2 receptor Tag-lite binding assay
- Quantity/Concentation; 0.15 nmol (dried). Suspend in 30µL DMSO to give a 5µM solution
- Molecular Weight: 2375.3

Assay Validation:
Bombesin B2 receptor ligand binding assay is performed by using the starter pack reagents.
Kd was determined, and signal inhibition (IC50) by agonist and antagonist was performed with L0019RED (Tag-lite Bombesin receptors red agonist) 1nM.
Results obtained with radioligand assay and Tag-lite platform were very similar
| Family | Receptor | Compounds | Radioactivity (Ki nM) |
Tag-lite (Ki nM) |
| Bombesin | BB2 | PD 168,368 (antagonist, organic) | 1173 nM (1) | 221.4 nM |
| [Pro1]-Bombesin (agonist-peptide) | 0.36 nM for Bombesin (2) | 0.24 nM |
