Allgemeine Beschreibung

Abberior STAR RED is a well-known red dye, named also KK114 in literature. It was developed for STED and confocal imaging in the red spectral region. It shows an exceptional brightness and low background, delivering stunning STED images. The dye works extremely well with Abberior Instruments STEDYCON and Expert Line microscopes and Leica STED microscopes. Abberior STAR RED can substitute dyes like Atto 647N, Alexa Fluor 647, or Cy®5. It can be excited with lasers at wavelength between 630 - 650 nm. For STED, a depletion wavelength around 750 - 800 nm is recommended. Abberior STAR RED is the ideal partner for Abberior STAR 580 to obtain optimal 2 Color STED results. Best results are obtained with freshly prepared samples.
