The image shows a portion of a slice through a 3D tomographic reconstruction of a mouse adenocarcinoma cell based on x-ray microscopy. Live cells were cryofixed by plunge freezing in liquid ethane and the vitrified material observed unstained using x-ray microscopy at a wavelength that yields high contrast between water and organic material. Images were taken over a range of specimen tilts from -60 to +60 degrees at 1 degree intervals. The image represents a 9.8 nm thick slice of the computed tomogram in the x-y plane, and shows a region of cytoplasm containing a Golgi apparatus. The image has a resolution of ~36 nm (Rayleigh Criterion) and ~70 nm (Fourier Ring Correlation), the latter corresponding to ~35 nm half-pitch resolution. Additional X-ray images from the study are included in this CIL Group.

Mouse adenocarcinoma cells were grown on gold grids coated with cellulose nitrate, incubated with 270 nm diameter gold-coated silica beads, plunge frozen in liquid ethane, transferred to a Gatan 630 cryoholder, and imaged at -170C in the frozen hydrated state using the X-ray microscope at the Helmholz Zentrum, Berlin, Germany. The microscope uses partially coherent illumination and a zone plate objective, and allows the specimen to be observed over a range of tilts. The images were aligned using the gold beads as fiduciary markers, and reconstructed using a reciprocal space algorithm.
