          Over View

          The instrument for quantitative cell biology at single-molecule detection.

          Stimulated Emission Depletion (STED) is a powerful microscopy technique that allows for the observation of fluorescence structure with spatial resolution below the diffraction limit. The Alba-STED uses the pulsed excitation and pulsed depletion approach (pSTED) in combination with the digital frequency domain fluorescence lifetime imaging (FastFLIM) to record the time-resolved photons which allows for an increase in the image resolution and the separation of two labels with the same excitation wavelength.

          Key Features of Alba-STED for FLIM/FFS:

          • pSTED (Pulsed excitation and pulsed STED)
          • FastFLIM for time-resolved pSTED acquisition
          • Improved image resolution using the phasor plot

          • Dual-label excitation
          • Fast image acquisition (dwell time: 0.2 µs)

          Confocal images of 60nm fluorescence beads (left); pSTED images (middle); sharpening the pSTED image using a binary filter based on the phasor plots (right).

          Dual labels can be separated using pSTED and FastFLIM. Atto 647N and Atto 655 were used as labels; they both are excited by the 640 nm laser. The two dyes are first separated using the phasor plots, and then assigned with two different false colors (Atto 647N - yellow, Atto 655 - purple) to produce the processed and merged pSTED image of the two labels.

          Options and Accessories available for Alba-STED for FLIM/FFS

          Non Descanned Detection (NDD) Port

          enlarge
          Detection through the Non Descanned Detection Port (NDD) is used in conjunction with multiphoton excitation; the fluorescence photons generated in the excitation spot of the laser are scattered back and collected right after the objective (without passing through the optics in the scanning path).

          The Figure displays the NDD port on the Nikon Model Ti microscope coupled to the Alba. A raiser is introduced on the Nikon microscope above the epifluorescence port for connecting the NDD port and adding the filters-cartridge where the dichroic filters for the NDD detection are inserted. The detectors are mounted on an orthogonal mount complete of dichroic and filter holders. The NDD port uses either GaAs PMTs or hybrid detectors. The output of the detectors is diverted either to the data acquisition unit.
          Laser Scanning Transmitted Detection Module with a Photon Counting PMT
          enlarge
          T-PMT is a transmitted detection module with a photon counting PMT that works with inverted microscopes.

          The module is installed beside the microscope transmission illumination lamp and features a manual slider for selecting between the PMT and the lamp illumination.
          Microscope Stages
          enlarge

          XYZ-stepper motor controlled stage for Microwell plates (8-, 96- and 384-wellplate)

          The XYZ stage provides high resolution, highly repeatable, and fast controls for the X, Y, and Z position of the microscope stage; it utilizes crossed-roller slides, a high-precision lead screw, and zero-backlash miniature geared DC servomotors for smooth and accurate motion. Controlled through the USB port, it is the ideal stage when measuring samples in a microwell plate.

          VistaVision includes protocols for the automatic measurement at single points (FFS, lifetime, polarization); the user can select the sequential measurements on all the wells; alternatively, a set of wells can be selected for the measurements.
