Abberior STAR 635 particularly well suits the Abberior Instruments 2-color 775nm STED microscope and the Leica TCS STED system. It delivers high-resolution STED images with very low background signal due to its improved water solubility and exceptional brightness. The dye serves as an ideal partner for several 2-color STED packages.

General description

Abberior STAR 635 is the latest dye development for STED imaging in the red spectral region. It features exceptional brightness and ultralow background, delivering stunning STED images. The dye works exceptionally well with the Abberior Instruments STED microscope as well as with the Leica STED microscope.
Abberior STAR 635 can substitute ATTO 647N, Alexa Fluor® 647, or Cy®5. It can be excited with diode lasers (635 nm, 650 nm) or with the 647 nm line of a Krypton laser. For STED, a depletion wavelength around 750-780 nm is recommended.

Best results are obtained with freshly prepared samples.
