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).

项目总结(见说明)： 电子显微镜核心(EM核心)容纳和维护所有仪器，特别是FEI Tecnai F30电子显微镜，其场发射枪工作电压为300千伏，用于记录流感病毒血凝素(HA)和中和抗体纤维之间的高分辨率图像。这些络合物将被分析为二十面体支架上的对称展示或HA玫瑰花环。它还包括另一台高分辨率仪器(一台FEI Tecnai F20，将在未来12个月内安装在布兰代斯)和两台用于样本筛选的较小仪器。电子显微镜将由陈煦博士(布兰代斯)负责维护。此外，EM Core还提供计算设施来处理图像数据并生成高质量的3D重建。詹姆斯·陈博士(Brandeis)将建立一条图像处理流水线，用于这些结构的中等吞吐量处理。
