CY3

CY3 is a fluorescent dye, which is derived from the cyanine family of compounds with a specific excitation/emission spectrum. It operates by fluorescing when exposed to certain wavelengths of light, typically around 554 nm for excitation and 568 nm for emission. This spectral property allows it to be used as a powerful molecular probe. The primary applications of CY3 revolve around biological labeling techniques, such as fluorescence microscopy and flow cytometry. It is used to label nucleic acids, proteins, or other cellular components, allowing for visualization and analysis of biological processes at the molecular level. CY3's stable and bright fluorescence makes it an ideal choice for single or multiplex labeling, facilitating detailed cellular and molecular studies. It is particularly favored in applications requiring long-lasting and intense fluorescent signals. In summary, CY3's utility in scientific research enhances our understanding of cellular dynamics and molecular interactions, contributing significantly to advances in areas such as genomics, proteomics, and cell biology.

CY3 (Sulfo-Cyanine3) is an orange-fluorescent label for nucleic acid and protein (λex=554, λem=568).
