DusQ 2 NHS Ester is a non-fluorescent dark quencher designed for fluorescence resonance energy transfer (FRET) applications. It features an N-hydroxysuccinimide (NHS) ester functional group, enabling efficient conjugation to primary amines in biomolecules such as proteins, peptides, and oligonucleotides.
Key Features:
- Absorption Maximum: 552 nm
- Quenching Range: 560–670 nm
- Functional Group: NHS ester for amine-reactive conjugation
Applications:
- FRET Assays: Serves as an acceptor for fluorophores emitting in the yellow to red spectrum, including Cyanine3, TAMRA, and ROX.
- Multiplex Assays: Ideal for complex assays due to its lack of secondary fluorescence.
- Bioconjugation: Efficiently labels amine-containing biomolecules for various analytical and diagnostic purposes.
