Product Introduction
Cyanine3.5 NHS ester tetrafluoroborate is a fluorescent labeling reagent used for bioconjugation. It contains a Cyanine3.5 (Cy3.5) fluorophore activated as an N-hydroxysuccinimide (NHS) ester, with tetrafluoroborate as the counterion. The NHS ester group reacts with primary amines to form stable amide bonds, enabling efficient labeling of proteins, peptides, antibodies, and amino-modified oligonucleotides. It is widely used in fluorescence microscopy, flow cytometry, microarray analysis, and other molecular biology applications.
