Product Introduction
Sulfo-Cyanine7 NHS ester is a reactive dye that features an N-hydroxysuccinimide (NHS) ester group, facilitating its conjugation to primary amines on biomolecules. This reagent is commonly used in bioconjugation and labeling applications, where its sulfonated cyanine dye structure provides excellent water solubility and strong near-infrared fluorescence. Sulfo-Cyanine7 NHS ester is incorporated into experiments requiring precise fluorescent tagging of proteins, peptides, or other amine-containing substrates, supporting advanced imaging and detection techniques in biochemical research.
