Use a bright luciferase for bioluminescence resonance energy transfer to explore protein: protein interactions

Highly sensitive NanoBRET measurements using the LVF monochromator or filter-based readers

With the NanoLuc ® luciferase, Promega has created the next generation of BRET assays. The NanoLuc ® enzyme is smaller in size than other luciferases. At the same time its emission is brighter by several factors. These properties make the NanoLuc ® the perfect BRET donor . As BRET acceptor, a fluorescently labeled fusion protein are used such as the HaloTag ® that emits light in the red range (> 610 nm).

The NanoBRET assay technology is intended for studying protein-protein interactions in living cells. The proteins of major interest are membrane receptors such as G-protein coupled receptors (GPCR) and receptor tyrosine kinases (RTK).

All BMG LABTECH microplate readers can be equipped with optimized filters to record the two BRET signals coming from NanoLuc ® luciferase and fluorophore.

The CLARIOstar ® with its linear variable filter (LVF) monochromator ™ matches the two NanoBRET wavelengths without special filters. The flexibility to use the LVF monochromator for NanoBRET ™ measurements enables discrimination of donor of luminescence and two different acceptor fluorophores. This features a novel receptor internalization assay .
