TEM is a microscopy technology technique where an electron beam is transmitted through ultrathin specimen, interacting with the specimen as the electron beam passes through it, resulting in the formation of living image. Then the image is magnified and focused onto an imaging device, such as a fluorescent screen, on a layer of photographic film, or to be detected by a sensor such as a CCD camera. All samples prepared for TEM must be small and thin enough to be electron transparent, which is comparable to the mean free path of the electrons that travel through the samples. In addition, all water must be removed from the samples as the TEM requires vacuum environment.
Some products (such as films and wax) have different sizes: please feel free to contact us for any inquiries. Creative Biostructure also provides various custom UniCrys™ membrane protein crystallization services and products for SEM and cryo-EM. Please feel free to contact us for a detailed information.
