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.

Cy2 is a cyanine dye used for labeling amino groups in oligonucleotides, peptides, and proteins (λ excitation: 488 nm; λ emission: 520 nm).

TFAX 594,SE is a red fluorescent dye that maintains its fluorescence properties across a pH range of 4 to 10. It produces highly intense and photostable conjugates when bound to proteins or antibodies, such as [goat anti-mouse IgG].

AF647 NHS is a fluorescent dye commonly used for biomolecule labeling. It exhibits far-red fluorescence with Ex Em(nm)= 648nm 671nm. The active ester group of this dye reacts with amino groups (mainly primary amines) on target biomolecules, forming stable amide bonds, thus labeling AF647 fluorescent molecules onto biopolymers.

Sulfo-Cyanine7 is an improved analog of Cy7 fluorophore with quantum yield improved by 20%, and higher photostability. This fluorescent dye is especially useful for NIR imaging.

Cyanine7.5 carboxylic acid chloride, a dye derivative of Cyanine 7.5 (Cy7.5) featuring carboxylic acid functional groups, is a near-infrared fluorescent dye used primarily in biomedical research for applications like biomarkers and cell imaging. It can covalently bind to biological molecules (especially antibodies, proteins, etc.) to monitor their location and dynamic changes in biological samples.

Cyanine5.5 maleimide chloride, a CY dye, is a compound characterized by two nitrogen atoms connected by an odd number of methyl units. CY dyes exhibit long wavelengths, adjustable absorption and emission, high extinction coefficient, good water solubility, and relatively simple synthesis [1]. They are commonly used for labeling proteins, antibodies, and small molecules. For protein antibody labeling, the combination can be achieved through a simple mixing reaction, which has reference significance [2].
