Cy5.5 is a near-infrared fluorescent dye for labeling biomolecules such as peptides, proteins and oligonucleotides (Ex=673 nm, Em=707 nm)[2].

Cy5.5 acetate is a CY dye, where CY stands for cyanine—an organic compound comprised of two nitrogen atoms linked with an odd number of methine units. Cyanine compounds are known for their long wavelengths, adjustable absorption and emission, high extinction coefficients, good water solubility, and relatively simple synthesis. CY dyes are frequently used for labeling proteins, antibodies, and small molecules. For protein and antibody labeling, the attachment can be achieved through a straightforward mixing reaction. Below, we outline a labeling method for proteins and antibodies, which may serve as a useful reference.

Cy5.5 TEA is a type of CY dye, where CY stands for Cyanine, a compound composed of two nitrogen atoms connected by an odd number of methine units. Cyanine compounds are characterized by long wavelengths, tunable absorption and emission, high extinction coefficients, good water solubility, and relatively simple synthesis. CY dyes are frequently utilized for labeling proteins, antibodies, and small molecules. For protein antibody labeling, coupling can be achieved through a straightforward mixing reaction. Below, we introduce a method for labeling protein antibodies that serves as a useful reference.

Sulfo-Cy5.5 is a near-infrared fluorescent dye (Ex=673 nm, Em=707 nm) that can be used to label biomolecules such as peptides, proteins, and oligonucleotides [2].
