CY series fluorescent dyes are divided into sulfonated cyanine dyes and non sulfonated Cyanines. Their spectral properties are basically the same, and their reactions with small protein molecules are basically the same. The difference lies in their solubility. The difference is as follows: non sulfonated cyanine dyes must be dissolved in organic solvents such as DMF or DMSO and added with buffered aqueous solutions. Sulfonated cyanine dye - dissolved in water, the whole use process is completely carried out in the water phase.

Cy5 labeled polyethylene glycol is a near-infrared fluorescent peg derivative with an absorption wavelength max of 650 nm and an emission wavelength of about 670 nm. Cy5 labeled PEG derivatives can be easily tracked from their blue and strong fluorescence. Sulfhydryl groups react with maleimide to form thioether bonds, and react with thiopyridine to form disulfide bonds, which can also be used to modify gold nanoparticles. Cy5-peg-sh is sensitive to light and temperature. In order to achieve the use effect, the material should always be kept under dry low temperature conditions. Avoid frequent thawing and freezing. Cyanine dyes (CY) are a kind of fluorescent dyes commonly used in the near-infrared fluorescent dyes. The autofluorescence of cells and tissues is small in the near-infrared band, which can provide higher specificity and sensitivity.
