Cyanine3 NHS ester

Cy3 NHS ester is a fluorescent dye used to label amino groups in proteins, peptides, antibodies, and oligonucleotides. The excitation emission (Ex Em) values ​​of Cy3 NHS ester are 550 nm 570 nm.

Cyanine3 NHS Ester Tetrafluoroborate is a fluorescent labeling reagent containing Cy3 fluorophore, NHS ester active group and tetrafluoroborate stabilizer. Cyanine3 NHS Ester Tetrafluoroborate can react with amino groups on biological molecules and is used in biological analysis fields such as protein, antibody, nucleic acid labeling and cell imaging.

Sulfo-cyanine3 NHS ester sodium, a water-soluble cyanine dye, features NHS ester groups that are amino-reactive.

CY3-SE (Sulfo-Cy3 NHS ester) is a reactive dye for the labeling of amino-groups in the soluble proteins, peptides, and oligonucleotides DNA (Excitation: 555 nm, Emission: 570 nm).

BDP 558 568 NHS ester, a borondipyrromethene fluorophore, emits in the yellow part of the spectrum. It is an amine-reactive NHS ester with absorption and emission spectra analogous to TAMRA, BDP TMR, Cyanine3, and sulfo-Cyanine3 [1] [2].
