Tocris Bioscience™ CELT-133

Description

CELT-133 is a selective hα1A adrenergic receptor fluorescent antagonist. It shows full selectivity for α1A over α2A (Ki= 5 nM and 15% of displacement at 1 μM respectively in radioligand binding assay). CELT-133 binds equally to all subtypes of α1 adrenergic receptor. Excitation and emission maxima (λ) are 560 and 571 nm, respectively. Wavelengths are compatible with use as an acceptor dye in TR-FRET assays, together with the CoraFluor™ 1 (Cat. No. 7920) TR-FRET donor. Add 76 μL of assay buffer containing 1% of DMSO to obtain a 100 μM stock solution, and use 250 nM as a working concentration.
