What color is Cyanine Cy3?

Cyanine Cy3 Dye

Cyanine Cy3 dye is a synthetic dye belonging to the cyanine dye family, widely used in various biological and chemical applications for its fluorescent properties. The color of Cyanine Cy3 dye, when observed under normal lighting conditions, appears as a dark, almost crimson or cherry red. However, its fluorescence emission is what makes it particularly valuable in scientific research.

Fluorescence Properties

When excited by light, Cyanine Cy3 dye emits a bright, fluorescent light in the yellow to orange spectrum. Specifically, it has an excitation maximum typically around 550 nm and an emission maximum around 570 nm. This characteristic bright fluorescence allows for the visualization and tracking of molecules and cells in a variety of experimental settings.

Applications

Cyanine Cy3 dye is extensively used in molecular biology, biochemistry, and medical diagnostics. Its applications include fluorescence microscopy, flow cytometry, and fluorescence-based assays where it serves as a fluorescent marker for proteins, nucleic acids, and other biomolecules.

Advantages

  • High Fluorescence Intensity: Provides clear, bright signals for easy detection.
  • Stable: Exhibits good photostability, making it suitable for experiments requiring prolonged observation.
  • Versatile: Compatible with a wide range of detection equipment.

Note: While Cyanine Cy3 dye is invaluable in research, it is important to handle it with care, following all safety guidelines to avoid exposure and contamination.
