一般說明

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 propose a new type of scanning fluorescence microscope capable of resolving 35 nm in the far field. We overcome the diffraction resolution limit by employing stimulated emission to inhibit the fluorescence process in the outer regions of the excitation
