24A Soft X-ray Tomography

Beamline Description

24A is a full-field transmission soft X-ray tomography beamline. Microscopy includes an on-line correlation of fluorescence structured-illumination microscopy (SIM) with soft X-ray tomography (SXT), which is dedicated to image frozen-hydrated biological specimen with a spatial resolution of 15-30 nm for 2D imaging and 50 nm for 3D tomography.

Unique Features

To image 3D cellular strustures by the correlation of fluorescence structured-illumination microscopy with soft X-ray tomography.

Scientific Opportunities

  • Molecular events within cells: aggregation of misfolded proteins in cells.
  • Sub-cellular organelles: endocytosis, exocytosis, cell migration and cellular changes upon stimulation.
  • Cell-cell interaction and communication: neurological synapse and immunological synapse.
  • Host-microbe interaction: virus and intracellular bacteria.
