TetrahymenaFixationforTransmissionElectronMicroscopy
Tetrahymena Fixation for Transmission Electron MicroscopyPellet Tetrahymena cells in a clinical centrifuge.OPTIONAL: Suspend cells in HNMK (50 mM HEPES, pH 6.9, 36 mM NaCl, 0.1 mM Mg acetate, 1 mM KCl ) for 10-20 min at room temperture. This will remove precipitates present in the proteose peptone and provide cleaner surfaces if cells are processed for SEM.Pour off most of the medium and suspend cells in a slurr......阅读全文

电子探针仪与扫描电镜有何异同
透射电子显微镜 (transmission electron microscopy﹐简写为TEM)。 构造原理 : 电子显微镜的构造原理与光学显微镜相似﹐主要由照明系统和成像系统构成(图1 光学显微镜与电子显微镜的对比 )。照明系统包括电子枪和聚光镜。钨丝在真空中加热并在电场的作用下发射出电

材料形貌分析
相貌分析的主要内容是分析材料的几何形貌,材料的颗粒度,及颗粒度的分布以及形貌微区的成份和物相结构等方面。形貌分析方法主要有:光学显微镜(Opticalmicroscopy,OM)、扫描电子显微镜(Scanningelectron microscopy, SEM)、透射电子显微镜(Transmis
光合电子传递-(photosynthetic-electron-transport)
光合作用中,受光激发推动的电子从 H2 O到辅酶Ⅱ( NADP )的传递过程。光合色素吸收光能后,把能量聚集到反应中心——一种特殊状态的叶绿素 a分子,引起电荷分离和光化学反应。一方面将水氧化,放出氧气;另一方面把电子传递给辅酶Ⅱ( NADP ),将它还原成 NADPH,其间经过一系列中间(电
EBSD分析(electron-backscatter-diffraction)是指
EBSD即电子背散射衍射。EBSD的原理始于20世纪50年代,技术问世于80年代。EBSD是扫描电子显微镜(SEM)的一个标准分析附件,但大大拓宽了扫描电子显微镜进行微观分析的功能。它可以与SEM的其他功能(包括EDS等配件)结合起来,原位成像、成分分析、大样品分析、粗糙表面成像等,克服了传统分析方

补体结合反应(complement-fixation-test)技术概况
可溶性抗原,如蛋白质、多糖、类脂质和病毒等,与相应抗体结合后,抗原抗体复合物可以结合补体,但这一反应肉眼不能察觉,如再加入红细胞和溶血素,即可根据是否出现溶血反应来判定反应系统中是否存在相应的抗原或抗体。这个反应就是补体结合反应。 补体结合反应是一种古老的血清学技术,Bordet和Gengou在19
