| Application: | Abberior™ STAR RED labelled cholesterol analogs were used for STED-FCS (stimulated emission depletion - fluorescence correlation spectroscopy) based measurements of membrane diffusion dynamics. Anti-mouse secondary antibody coupled to Abberior™ STAR RED has been used for STED microscopy imaging in Vero cell line. |
| General description: | Abberior STAR RED is an already well known dye named also KK114 in literature (a scientific web search shows more than 60 publications, a selection is listed below). Please note the minimal background signal due to negligible unspecific binding. A key feature of the dye is its comparably long lifetime of ~3.5ns. The dye works exceptionally well with the Abberior Instruments STED microscope as well as with the Leica STED microscope. Abberior STAR RED can substitute Atto™ 647N, AlexaFluor 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 nm is recommended. Please see reference [2] for detailed characteristics. Best results are obtained with freshly prepared samples. |
