An amine-reactive sulfonated cyanine dye for fluorescent labeling of proteins, peptides and amino-modified oligonucleotides.
Energybiopharma Sulfo-Cy5.5 NHS Ester (ENG-CY007) contains an activated N-hydroxysuccinimide ester for conjugation to primary amino groups. It supports the preparation of fluorescently labeled proteins, peptides and amino-modified oligonucleotides.
The manufacturer reports excitation and emission wavelengths of 687/706 nm, making this reagent useful for developing long-wavelength fluorescent conjugates. Labeling conditions should be optimized for the target molecule, and moisture exposure should be minimized to preserve NHS ester reactivity.
