An amine-reactive cyanine fluorescent dye for labeling proteins, peptides and amino-modified oligonucleotides.
Cy5.5-SE is a sulfonated cyanine dye containing an activated N-hydroxysuccinimide (NHS) ester. This reactive group enables conjugation to primary amino groups, supporting the preparation of fluorescently labeled biomolecules.
The dye can be used to develop fluorescent conjugates for imaging and biochemical detection studies. Labeling conditions should be optimized for the target molecule, and moisture exposure should be minimized to preserve NHS ester reactivity.CAS NO.:442912-55-2 – GlpBio
