Cat. No. List below
Description
FSD Fluor™ 647 NHS ester is a next-generation, far-red fluorescent dye developed by BioActs. It offers superior optical properties compared to spectrally similar dyes, making it ideal for various biochemical and biological analytical applications.
FSD Fluor™ 647 NHS ester is optimized for labeling antibodies, peptides, proteins, ligands, and amplification substrates. These applications are particularly suited for cellular labeling and detection.
Elevate your fluorescence-based experiments with FSD Fluor™ 647 NHS ester and experience the difference in brightness, stability, and overall performance that only next-generation fluorophore technology can deliver. NHS esters readily react with amine-modified oligonucleotides or amino groups of proteins, i.e. the ε-amino groups of lysine or the amine terminus of nucleotides to form a chemically stable amide bond between dye and the biomolecule.
What are the advantages?
1. High Fluorescence Intensity: Excellent brightness after binding to biomolecules such as antibodies, nucleotides, and proteins.
2. Photostability: Enhanced stability for reliable and long-lasting fluorescence signals.
3. Single-Molecule Detection: Ideal for fluorescence correlation spectroscopy and fluorescence polarization measurements.
4. Reactivity: NHS esters readily react with amine-modified oligonucleotides and amino groups of proteins to form stable amide bonds.
