说明： Terbium cryptate FRET donor for TR-FRET assay development; amine reactive for conjugation
生物活性 for CoraFluor™ 1, amine reactive
CoraFluor™ 1, 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. This product is designed with a PFP ester for reactivity with primary amines, 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, amine 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, thiol reactive and CoraFluor™ 2, amine reactive also available.
Please refer to the protocol for further information on conjugation.
CoraFluor™ is a trademark of Bio-Techne Corp.
