The 54-kDa subunit SRP54 of the signal recognition particle in eukaryotic cells is responsible for the recognition of nascent proteins destined for secretion or membrane integration. The three-dimensional structure of this protein was determined usin

One of the main applications of an energy filter is to obtain elemental distribution images by electron spectroscopic imaging. This technique has been pushed to the imaging of fine structure such as the sp2 and sp3 states of carbon at a sub-nanometer

Electron microscopy produces 2D images of 3D objects with resolutions generally from about 2-5 nm for stained or shadowed specimens, to as good as 0.3-0.5 nm for unstained specimens using bright field or dark field techniques. Many groups have worked

The electron microscopic extraction of information from biological specimens has always been a compromise among at least four factors: resolution, contrast, radiation damage and signal-to-noise ratio. To overcome the notoriously low contrast of most

The signal recognition particle (SRP) is a ribonucleoprotein consisting of six distinct polypeptide components and one molecule of small cytoplasmic RNA (7SL RNA). The particle was previously shown to function in protein translocation across and prot

A prism-mirror-prism energy filter installed in a transmission electron microscope was used to examine oxide films formed on zirconium. Bright and dark-field images were obtained using electrons which were elastically and inelastically scattered. Rep

A new imaging modality in electron microscopy uses energy filtration to produce micrographs with elastically scattered electrons or with electrons that have lost a specific, often characteristic amount of energy in interacting with the specimen. No d
