Cy2 is a green fluorescent dye. It is the only dye in the Cy series with benzooxazole as the chromophor, because of this, although it has the same length of the methyl-bridge chain as Cy3, its absorption peak and emission peak shift by about 70 nm to reach the yellow-green spectral region, making it the only dye in the Cy series to emit green fluorescence. Cy2 has many advantages, including strong fluorescence in both non-polar and polar environments, support for non-polar organic sealers such as DPX and Permount, stable fluorescent nuclear chemical structure, suitable for green fluorescent channels of various conventional instruments, and labeling of various nanomaterials and biological samples.
CY is the abbreviation of Cyanine, the classic cyanine dye contains two nitrogen-containing heterocyclic rings, the molecule contains a conjugated chain composed of methylchuan (CH) n, n can be odd or even. This property can significantly affect their electronic structure in the electron ground state of the equilibrium structure, both ends of the conjugated chain or in the middle of the chain are connected with heterocyclic ring, aromatic ring compounds, cycloalene compounds and conjugated chains to form a large conjugated system, the hydrogen inside the molecule can be replaced by a certain number of various substituents. CY dyes are often used for the labeling of proteins, antibodies and small molecule compounds. For the labeling of protein antibodies, the binding can be completed through a simple mixing reaction.
Cy series belongs to cyanine dyes, among which Cy SE is an insoluble form and Sulfo-Cy SE is a highly water-soluble form of sulfonic acid.
