Abstract
Electron Microscope Laboratory in Riken CDB has been providing support activities on electron microscopy (EM) while original researches have been also performed. The activities include maintenance of equipments such as electron microscopes, consultation about EM analysis and procedures ranging from sample fixation to image recording. We also train researchers' skills of electron microscopy. Clients are both inside and outside CDB. We contact clients during our EM analysis quickly and frequently using email with attached files of images taken with CCD camera. Samples include model animals such as C. elegans, drosophila, mouse or tissue culture cells. Although support activities like ours appear to become increasingly important for analysis of knockout mice or differentiated cells from ES or iPS cells, we still have no promising way to bring up human resources for EM analysis.
