Description
Cy5 maleimide, a CY dye where CY represents Cyanine, comprises two nitrogen atoms linked by an odd number of methyl groups. Characteristics of Cyanine compounds include long wavelength, tunable absorption and emission, high extinction coefficient, favorable water solubility, and straightforward synthesis . Commonly utilized in the labeling of proteins, antibodies, and small molecular compounds, CY dyes facilitate the attachment to protein antibodies via a simple mixing reaction, a method that holds notable reference value . Storage recommendation: protect from light.
