Description: Terbium cryptate FRET donor for TR-FRET assay development, cysteine reactive for conjugation
Biological Activity for CoraFluor™ 1, thiol reactive
CoraFluor™ 1, thiol 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. This product is designed with maleimide functionality to conjugate to cysteines, making it suitable for labeling biomolecules, including antibodies, nanobodies, proteins and peptides. It is exceptionally bright, providing unmatched assay sensitivity and stability in biological media over other commercially available TR-FRET donors. CoraFluor™ 1, thiol reactive is compatible with common acceptor dyes such as FAM, TMR and Cyanine 5, SE (Cat. No. 5436), enabling seamless assay integration in high throughput screening applications.
CoraFluor™ 1, amine reactive and CoraFluor™ 2, amine reactive also available.
Please refer to the protocol for further information on conjugation.
