Imaging of Self‐Assembled Structures: Interpretation of TEM and Cryo‐TEM Images [PDF]
Angewandte Chemie - International Edition, 2010 AbstractThe investigation of solution‐borne nanostructures by transmission electron microscopy (TEM) is a frequently used analytical method in materials chemistry. In many cases, the preparation of the TEM sample involves drying and staining steps, and the collection of images leads to the interaction of the specimen with the electron beam.

Sequences of the Genes for the TEM-20, TEM-21, TEM-22, and TEM-29 Extended-Spectrum β-Lactamases [PDF]
Antimicrobial Agents and Chemotherapy, 1999 ABSTRACT The sequences of the bla TEM genes encoding TEM-20, TEM-21, TEM-22, and TEM-29 extended-spectrum β-lactamases were determined. Analysis of the deduced amino acid sequences indicated that TEM-20 and TEM-29 were derived from TEM-1 and that TEM-21 and TEM-22 were derived from TEM-2.
