DNA-Binding Fluorescent Stain (Miami Green)

This fluorescent nuclear dye has been shown to be brighter than traditional nuclear stains (e.g., DAPI, Hoechst) in Human Embryonic Kidney (HEK) and breast cancer cells (MCF7). It is ideal for in vivo cell or tissue studies where prolonged imaging experiments are necessary.

 

Highlights:

  • Low cytotoxicity, membrane permeable, and live-cell compatible fluorescent probe
  • Increased sensitivity - Allows for lower dye loadings and/or illuminations intensities
  • π (Pi)-electronic system – Enables excitation at visible wavelengths
  • Rotatable arms – Permit for detection at common fluorescence microscope wavelengths
  • Cationic moieties – Allow for interaction with the phosphate backbone of DNA minor groove
