Biological Activity

CoraFluor™ 2, amine reactive is a terbium-based time-resolved Förster resonance energy transfer (TR-FRET) donor for TR-FRET assay development, such as target engagement and ternary complex assays. CoraFluor™ 2 is designed with a PFP ester for reactivity with primary amines, making it suitable for labeling biomolecules, including antibodies, nanobodies, proteins and peptides. CoraFluor™ 2 is cell permeable and can be used in live cell intracellular TR-FRET assays. It is exceptionally bright, providing unmatched assay sensitivity and stability in biological media over other commercially available TR-FRET donors. CoraFluor™ 2 displays red shifted excitation and is excitable by both 365 nm and 405 nm lasers, and is compatible with common acceptor dyes such as FAM/FITC, AF488, GFP and mCherry, enabling seamless assay integration in high throughput screening applications.

CoraFluor™ 1, amine reactive and CoraFluor™ 1, thiol reactive also available.

Please refer to the protocol for further information on conjugation.
