Abstract

PROJECT SUMMARY (See instructions): The electron microscopy core (EM Core) houses and maintains all the instrumentation, in particular an FEI Tecnai F30 electron microscope with a field emission gun operating at 300 kV, needed for the recording of high-resolution images of complexes between influenza virus hemagglutin (HA) and the Fabs of neutralizing antibodies. These complexes will be analyzed either as symmetrical displays on an icosahedral scaffold or as HA rosettes.. It also contains another high-resolution instrument (an FEI Tecnai F20 that will be installed at Brandeis during the next 12 months) and two smaller instruments for sample screening. The electron microscopes will be maintained by Dr. Chen Xu (Brandeis). Furthermore, the EM Core provides computing facilities to process the image data and produce high-quality 3D reconstructions. An image processing pipeline for medium throughput processing of these structures will be set up by Dr. James Chen (Brandeis).
