    Measuring ligand-cell surface receptor affinities with axial line-scanning fluorescence correlation spectroscopy

    Antonia Franziska Eckert et al.
    A robust fluorescence microscopy-based data acquisition and analysis framework affords the precise measurement of cell surface receptor affinities toward their cognate ligands and their densities in live cells/tissues.

    An improved fluorescent noncanonical amino acid for measuring conformational distributions using time-resolved transition metal ion FRET

    William N Zagotta et al.
    Time-resolved transition metal ion fluorescence resonance energy transfer using a fluorescent, noncanonical amino acid donor and metal ion acceptor measures distances and distance distributions in proteins, allowing the equilibrium distributions among conformational states to be accurately determined.

    Permeant fluorescent probes visualize the activation of SARM1 and uncover an anti-neurodegenerative drug candidate

    Wan Hua Li et al.
    The first-in-class cell-permeant fluorescent probe provides direct and visual evidence of SARM1 activation in axonal degeneration and identified the first covalent, allosteric inhibitor of SARM1 acting on the NAD-binding pocket in the ARM domain.

    Relationship between simultaneously recorded spiking activity and fluorescence signal in GCaMP6 transgenic mice

    Lawrence Huang et al.
    Simultaneous calcium imaging and cell-attached recording in GCaMP6 transgenic mice in vivo reveals spiking-fluorescence relationship that supports more refined inference of neuronal activities from calcium imaging data.

    A universal vector concept for a direct genotyping of transgenic organisms and a systematic creation of homozygous lines

    Frederic Strobl et al.
    In transgenesis assays involving diploid model organisms, two clearly distinguishable transformation markers embedded in interweaved, but incompatible Lox site pairs allow the systematic creation of homozygous transgenic lines and minimize the number of wasted animals.

    Effects of fluorescent glutamate indicators on neurotransmitter diffusion and uptake

    Moritz Armbruster et al.
    Fluorescent glutamate indicators distort the time course of neurotransmitter diffusion and uptake by competing with transporters, an important caveat to consider when using iGluSnFR and its analogs.

    Identification of a pre-active conformation of a pentameric channel receptor

    Anaïs Menny et al.
    Allosteric reorganizations of a bacterial channel receptor are mapped along the protein structure, using the site-directed bimane quenching fluorescence technique, through parallel real-time conformational and electrophysiological recordings.

    Mouse retinal cell behaviour in space and time using light sheet fluorescence microscopy

    Claudia Prahst et al.
    Improved 3D and 4D imaging of neurovascular processes across scales reveals new insights into eye disease mouse models and shows retinal vessels are significantly distorted using standard flat-mount confocal imaging.
