General description
Abberior STAR 470SX is the dye of choice for long Stokes STED applications in the orange fluorescent regime. The dye is particularly designed and tested for 2-color STED microscopy in combination with our STAR 635 using a single STED wavelength. The dye is our recommendation for usage in the Leica TCS STED Ti:Sa 2-color system.
Key Features
- Designed for STED microscopy at ~750 nm
- Long Stokes′ shift (>130 nm) for 2-color applications
- Tested in the Leica TCS STED Ti:Sa 2-color system
