Red Española de Microscopía Óptica Avanzada
Super Resolution/ Stimulated Emission Depletion microscopy (STED)
Achucarro Basque Center for Neuroscience, - Imaging Facility

Our Imaging Unit is equipped with a Leica TCS STED CW SP8 Super-resolution microscope, which is the first equipment of its kind in Spain. This is a state-of-the art confocal microscope that allows exploring details of brain tissue, below the limits of diffraction barrier with a purely optical approach, even on living samples in real time.

Its technology allows super-resolution optical sections, which can penetrate the samples, and allow the observation of dynamic cellular processes at the nanoscale. It is equipped with a white laser for a more flexible and precise excitation and a super-resolution system that solves structural details in the range of 70-80 nm in a sample double fluorescent labeling.
