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)

Application
Anti-Rabbit IgG-Abberior® STAR 488 antibody has been used as a secondary antibody:
- for fluorescent immunohistochemistry in prostate cancer cell lines, PPC-1 and TSU-Pr1
- for immunofluorescence in HeLa and monkey kidney COS-7 cells
- for STED (stimulated emission depletion) microscopy in OLN-t40-α-syn cells (oligodendroglial cells)

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

α-Synuclein (α-syn) positive glial cytoplasmic inclusions (GCI) originating in oligodendrocytes (ODC) are a characteristic hallmark in multiple system atrophy (MSA). Their occurrence may be linked to a failure of the ubiquitin proteasome system (UPS) or the autophagic pathway. For proteasomal

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

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
