General description
Abberior STAR 488 is the latest development for STED microscopy. It is a very bright green fluorescent dye that can be very effectively excited at the prominent 488 nm laser line. Abberior STAR 488 can substitute dyes like Oregon Green 488, Atto™ 488 or Alexa Fluor 488.
STED: The dye can most effectively be depleted in STED microscopy at 585-605 nm.
Abberior STAR 488 is the dye of choice for excitation at 488 nm. Even more, the dye is particularly signed and tested for 2-color STED microscopy in combination with our STAR 440SX rusing a 590nm laser. The dye has been very successfully tested in the Leica 2-color TCS STED CW microscope.
Key Features
Absorption Maximum, λmax: 503 nm (PBS, pH 7.4)
Extinction Coefficient, ε(λmax): 65′000 M-1cm-1 (PBS, pH 7.4)
Correction Factor, CF260 = ε260/εmax: 0.28 (PBS, pH 7.4)
Correction Factor, CF280 = ε280/εmax: 0.14 (PBS, pH 7.4)
Fluorescence Maximum, λfl: 524nm (PBS, pH 7.4)
Recommended STED Wavelength, λSTED: 585 - 605 nm
Fluorescence Quantum Yield, η: 0.89 (PBS, pH 7.4)
Fluorescence Lifetime, τ: 3.9 ns (MeOH)

Stimulation emission depletion (STED) microscopy breaks the spatial resolution limit of conventional light microscopy while retaining its major advantages, such as working under physiological conditions. These properties make STED microscopy a perfect tool for investigating dynamic sub-cellular processes in living

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
