詳細

Abberior STAR 470SX is the latest development of long-Stokes-Shift dyes for STED microscopy. The dye can be excited from 450 to 480nm. It can substitute dyes like Chromeo 494. For STED, a depletion wavelength ~750 nm is recommended. It is therefore well suited for 2-color STED imaging as implemented in the Leica TCS STED Ti:Sa microscope.

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

Quorum sensing (QS) signaling allows bacteria to control gene expression once a critical population density is achieved. The Gram-negative human pathogen Pseudomonas aeruginosa uses N-acylhomoserine lactones (AHL) as QS signals, which coordinate the production of virulence factors and biofilms. These

We report immunofluorescence imaging with a spatial resolution well beyond the diffraction limit. An axial resolution of approximately 50 nm, corresponding to 1/16 of the irradiation wavelength of 793 nm, is achieved by stimulated emission depletion through opposing lenses. We

Lens-based optical microscopy failed to discern fluorescent features closer than 200 nm for decades, but the recent breaking of the diffraction resolution barrier by sequentially switching the fluorescence capability of adjacent features on and off is making nanoscale imaging routine. Reported
