Abberior STAR 470SXP

Item number: ST470SXP

Abberior STAR 470SXP is a long Stokes-shift dye optimized for STED and confocal microscopy in the orange spectral range. It shows a Stokes-shift of approx. 130 nm. As all long Stokes-shift dyes, it shows board excitation and emission band: It can be excited between 450- 500nm and emits between 600- 700nm. For STED microscopy, Abberior STAR 470SXP can be most efficiently used with STED Laser wavelengths between 750 - 800 nm. Abberior STAR 470SXP is designed and tested for multicolor STED microscopy in combination with Abberior STAR 580 and Abberior STAR 635P using a single STED wavelength (775 nm). Abberior STAR 470SXP can substitute dyes like Chromeo494 or DY-480XL. The hydrophilic properties of Abberior STAR 470SXP conjugates reduce unspecific binding of this dye and thus decrease undesired background fluorescence. Best results are obtained with freshly prepared samples.
