Polarisation resolved TCSPC data of fluorophores with a bi-exponential fluorescence decay profile undergoing homo-FRET leading to a bi-exponential anisotropy decay profile was simulated in MATLAB with a time window of 12.5 ns for a simulated pulse repetition rate of 80 MHz. The model, before accounting for incomplete decays and a simulated instrument response function takes the form where is the fractional contribution of the long component of the intensity decay and is the peak intensity. The data was simulated for two detectors polarised parallel and perpendicular to the excitation light, i.e. and . Using Equation 14 , and . The model was convolved with a Gaussian IRF with a full width half maximum of 150 ps. The lifetimes of the fluorescence decay components were set to be and with a fractional contribution of the long component . The rotational correlation times were set to and , i.e. of the order expected for a fluorescent protein fusion construct undergoing homo-FRET. The pixel simulated image was split into three regions with initial anisotropy contribution of the short component set to 0.1, 0.2 and 0.3. In all three regions the total initial anisotropy . The initial intensity was set such that there were on average total integrated counts in each pixel and Poissonian noise was added to each decay using the MATLAB function poissrnd. These simulation parameters were chosen to approximate realistic values for cell imaging data, with the lifetimes selected to be similar to those of common cyan fluorescent protein variants such as ECFP and Cerulean [62] (link). In common with Experiment 5, a mean smoothing kernel was applied to each the image representing each time-bin of the data by convolution.

Cyan Fluorescent Protein
Cyan Fluorescent Protein
Cyan Fluorescent Protein (CFP) is a genetically engineered variant of the Green Fluorescent Protein (GFP) that emits light in the cyan region of the visible spectrum.
CFP is widely used as a fluorescent marker in cell biology and molecular biology studies, allowing researchers to visualize protein localization, interactions, and dynamics within living cells.
The blue-shifted emission spectrum of CFP, compared to GFP, makes it useful for multicolor fluorescence applications and FRET (Förster Resonance Energy Transfer) experiments.
Researchers can leverage the PubCompare.ai platform to effeciently discover the best protocols and optimize their Cyan Fluorescent Protein research, enhancing reproducibility and accuracy through the power of AI-driven analysis.

Slices were superfused with 95% O2/5% CO2-bubbled aCSF containing 4 μm dipicrylamine (DPA; City Chemical, LLC) and 1 μm strychnine for 30 min before experiments. DPA partitions into the cell membrane and its voltage-induced movement modulates a Förster resonance energy transfer interaction with the cerulean fluorescent protein (CeFP) of the hVOS probe to give a voltage-sensitive fluorescent signal (Chanda et al., 2005 (link); Wang et al., 2010 (link)). Bath temperature was measured between the inflow of the chamber and the tissue with a microprobe thermometer. An inline heater warmed the aCSF just before it reached the chamber to keep the temperature between 28°C and 31°C. hVOS imaging was conducted with an Olympus BX51 microscope equipped with a 29-W, 435 nm LED light source (Prizmatix), a standard cyan fluorescent protein filter set, and an Olympus XLUMPlanFl 20× objective (NA 1.0) or LUMPlanFl 60×objective (NA = 0.90). Images were acquired with a CCD-SMQ camera (Redshirt Imaging, now SciMeasure) at 2000 fps with 80 × 80 resolution. A computer program, either Neuroplex (SciMeasure) or an in-house program (Chang, 2006 ), controlled the timing of illumination, stimulation, and data acquisition. hVOS images were acquired as averages of 5–10 trials at 15-s intervals.

Male and female C57BL/6J mice of 8 to 12 wk of age were obtained from an in-house breeding colony within the QBP animal house (The University of Queensland) or from the animal resources centre (Murdoch, WA). Mac-Hdac7 mice, which overexpress HDAC7 in myeloid cells, have previously been described (11 (link)). Littermate MacBlue mice expressing cyan fluorescent protein (CFP) in myeloid cells (79 (link)) were used as controls for studies using Mac-Hdac7 mice. Myeloid-deleted Hdac7 mice (Hdac7−/−) (11 (link)) were obtained by crossing Hdac7flox/flox/LysMCre mice with Hdac7flox/flox mice, with littermate Hdac7flox/flox (Hdac7+/+) mice used as controls (80 (link)). As an additional control to ensure that the LysMCre allele did not confound data interpretation, functional assays (IL-1β release by ELISA, Escherichia coli-induced ROS production, and intracellular UPEC loads in macrophages) were performed to compare the phenotypes of BMM from LysMCre, Hdac7+/+, and Hdac7−/− mice (SI Appendix, Fig. S9 A–D ). Tlr4−/− mice (81 (link)) were maintained on a C57BL/6J background at the QBP animal house.

Leaves of Nicotiana tabacum cv. Xanthi were transformed by agroinfiltration (Norkunas et al., 2018 (link)) with the Agrobacterium tumefaciens strain GV3101 containing an overexpression cassette for VvLYK1-1, VvLYK1-2, VvLYK5-1, or VvLYK5-2 fused with either a C-terminal Cyan Fluorescent Protein (Cter-CFP in the pH7CWG2 plasmid, Karimi et al., 2005 (link)) or a C-terminal Yellow Fluorescent Protein (Cter-YFP in the pH7YWG2 plasmid, Karimi et al., 2005 (link)). Five days after (co-)infiltration, the abaxial side of N. tabacum leaves transiently expressing the different constructs was infiltrated with chitin or water (mock treatment). Observations were performed 30 min post-treatments (according to Cheval et al., 2020 (link)) using a Nikon A1-MP multiphoton microscope with an Apo IR x60 objective (NA: 1.27, water immersion, Nikon). Fluorescence lifetime imaging (FLIM) images were collected using a time-correlated single-photon counting (TCSPC) module (Picoquant). CFP excitation (820 nm with two-photon excitation) was provided by an IR laser (Chameleon, Coherent) delivering femtosecond pulses at a repetition rate of 80 MHz. Its resulting fluorescence emission was collected with a single photon avalanche diode (SPAD), using a band-pass emission filter FF01-494/20 (Semrock). TCSPC lifetime recording was performed over 200 temporal channels (final resolution: 0.64 ps). The FLIM analysis was performed on regions of interest (ROIs) drawn on the plasma membrane using the SymPhoTime (PicoQuant) software. Fluorescence lifetime values were calculated by fitting the tail of the CFP fluorescence decay with a bi-exponential model. Among the two generated lifetime constants (τ1 and τ2), only τ1 was reported, as it was the most sensitive to the Förster resonance energy transfer (FRET) (Bègue et al., 2019 (link); Rosnoblet et al., 2021 (link)). The efficiency of the energy transfer was given by the following equation: , with FDA and FD representing the relative fluorescence lifetime of the donor in the presence or the absence of the acceptor, respectively. Three independent experiments were conducted.

A bimolecular fluorescence complementation (BiFC) assay was performed by referring to the method described by Kang et al. (85 (link)). A. tumefaciens GV3101 cells containing different paired plasmids (different combinations of pSPYCE and pSPYNE-R or their derivatives) were cultured in Luria-Bertani (LB) liquid medium, collected by centrifugation, resuspended in infiltration buffer, and then mixed, followed by the adjustment to an optical density at 600 nm (OD600) of 0.5; they were then used to transform the A. tumefaciens GV3101 (pMP90) strains, respectively. After incubation for 2 to 4 h at room temperature, the A. tumefaciens GV3101 mixture was injected into the leaves of 6-week-old Nicotiana benthamiana plants. Subsequently, the fluorescence was assayed at 3 to 5 days after infiltration using a laser-scanning microscope with cyan fluorescent protein (CFP; excitation wavelength, 405 nm; emission wavelength, 477 nm).
