Viral DNA trafficking in cells has large impacts on physiology and disease development. Current methods lack the resolution and accuracy to visualize and quantify viral DNA trafficking at single-molecule resolution. We developed a noninvasive protocol for accurate quantification of viral DNA-genome
Linda Westin et al.
BMC neuroscience, 15, 45-45 (2014-03-29)
Norbin is a neuron-specific, cytosolic protein that interacts with the metabotropic glutamate receptor 5 (mGluR5) and has a profound impact on mGluR5 signaling. Yet, little is known about its synaptic distribution. Here we have analyzed the spatial relationship between Norbin

Vertebrates can sense and identify a vast array of chemical cues. The molecular machinery involved in chemodetection and transduction is expressed within the cilia of olfactory sensory neurons. Currently, there is only limited information available on the distribution and density

Optics letters, 19(11), 780-782 (1994-06-01)
We propose a new type of scanning fluorescence microscope capable of resolving 35 nm in the far field. We overcome the diffraction resolution limit by employing stimulated emission to inhibit the fluorescence process in the outer regions of the excitation
Marcus Dyba et al.
Nature biotechnology, 21(11), 1303-1304 (2003-10-21)
We report immunofluorescence imaging with a spatial resolution well beyond the diffraction limit. An axial resolution of approximately 50 nm, corresponding to 1/16 of the irradiation wavelength of 793 nm, is achieved by stimulated emission depletion through opposing lenses. We
