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.

Correction Factor, CF260 = ε260/εmax: 0.69
Correction Factor, CF280 = ε280/max: 0.47
Fluorescence Maximum, λfl: 609 nm (MeOH),
627 nm (PBS, pH 7.4)
Recommended STED Wavelength, λSTED: 740 - 770 nm
Fluorescence Quantum Yield, η: 0.80 (EtOH)
Fluorescence Lifetime, τ: 3.9 (EtOH)

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

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

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

We overcame the resolution limit of scanning far-field fluorescence microscopy by disabling the fluorescence from the outer part of the focal spot. Whereas a near-UV pulse generates a diffraction-limited distribution of excited molecules, a spatially offset pulse quenches the excited
