Dealing with backgrounds ¶ In some cases, the background intensity B might be present in the measured FLIM data, i.e. a background decay that is due to the sample preparation or instrument, and therefore should be included as an additional component in the Time-domain widefield FLIM based on gated cameras 7, optical intensifiers 8,9,10, and more recently TCSPC detection using crossed delay line anode detection 11 and single photon avalanche diode The phasor plot, also known as the AB plot or the polar plot (2-6), is a graphic representation of the raw FLIM data. Transforming FD or TCSPC FLIM data into the phasor plot is described below. 3.1 The phasor plot for FD FLIM data For one modulation frequency (ω), the FD FLIM data measurements at each pixel location are composed of both the Stand-alone TCSPC modules Remote control via TCP/IP interface (software handshake with ZEN and NIS Elements) Routing: 1 to 8 detectors: Measurement modes: Single point, multi-point, 2D imaging (XY, XZ, YZ), 3D imaging (XYZ), time lapse (XYT), oscilloscope mode for alignment purposes: Measurement previews: FLIM, FCS, FLCS and FCCS, Time Trace Get flim_data_stack and intensity_image from raw TTTR data.

Fluorescence-lifetime imaging microscopy or FLIM is an imaging technique based on the differences in the exponential decay rate of the fluorophore from a sample. It can be used as an imaging technique in confocal microscopy, two-photon excitation microscopy, and multiphoton tomography.

Modular Systems Unsurpassed in Time Resolution. Becker & Hickl continues to advance techniques of Time-Correlated Single Photon Counting (TCSPC) and Fluorescence Lifetime Imaging Microscopy (FLIM) with its family of high performance, high speed electronic modules.

If the FRET donor molecule has a single exponential decay kinetic, not only the FRET efficiency can be determined in every pixel of the image, but also the fraction of the FRET amplitude on the total decay, which is an indicator of the percentage of molecules undergoing FRET. Response: The FLIM script is applied to the file CENP-labelled_cells_for_FRET.ptu.Thereby, a new Window opens: Note: The window contains five different regions: Upper left: Imaging analysis options. Upper center: Fast FLIM image, displayed in false color scale.

Alternatively, FLIM data can be acquired using the TCSPC method, or both methodologies can be implemented on the same instrument. SP8 FALCON (FAst Lifetime CONtrast) is a fast and completely integrated fluorescence lifetime imaging microscopy (FLIM) confocal platform.SP8 FALCON delivers video-rate FLIM with pixel-by-pixel quantification, thanks to a novel concept for measuring fluorescence lifetimes built on fast electronics and sensitive spectral hybrid detectors.

It can be used as an imaging technique in confocal microscopy, two-photon excitation microscopy, and multiphoton tomography. Time-Correlated Single Photon Counting (TCSPC) is used to determine the fluorescence lifetime. In TCSPC, one measures the time between sample excitation by a pulsed laser and the arrival of the emitted photon at the detector. Excitation and detection in the wavelength range above 800nm is a convenient and relatively inexpensive way to increase the penetration depth in optical microscopy. Moreover, detection at long wavelength avoids the problem that tissue autofluorescence contaminates the signals from endogenous fluorescence probes.

Note: once NEXT CODE block is executed raw TTTR data variables (sync, tcspc, channel, special) are deleted. flim_data_stack: (pixX, pixY, spectral_detection_channel, tcspc_bins) Phasor FLIM is a very powerful analysis tool for molecular species separation and FRET analysis, in particular when the donor has a multi-exponential lifetime, something which is typical of CFP [cyan fluorescent protein] (Caiolfa et al., 2007). The Leica D FLIM an MP FLIM systems are add-ons of the TCS SP2 and TCS SP5 laser scanning microscopes. The systems are based on the multi-dimensional TCSPC technique [18] and the SPC-830 TCSPC modules of Becker & Hickl. This handbook should be consid-ered a supplement to the handbooks of the Leica TCS SP2, Leica TCS SP5, and the bh TCSPC fluorescence lifetime imaging microscopy, FLIM). Aber auch die Analyse des zeitlichen Verhaltens von gepulsten oder modulierten Lichtquellen ist damit möglich, bis hin zur Charakterisierung von umlaufenden Elektronenpaketen in Speicherringen von Synchrotronen anhand der abgegebenen Synchrotronstrahlung .
