General description
STED: The dye can most effectively be depleted in STED microscopy at 585-605 nm.
Abberior STAR 488 is the dye of choice for excitation at 488 nm. Even more, the dye is particularly signed and tested for 2-color STED microscopy in combination with our STAR 440SX rusing a 590nm laser. The dye has been very successfully tested in the Leica 2-color TCS STED CW microscope.
Key Features
- STED dye of choice at 488 nm excitation
- Ideal depletion behavior in STED microscopy ~590 nm
- 2-color labeling partner with STAR 440SX for 2-color STED microscopy
