FixationandEmbeddingofMicrotubulesforElectronMicroscopy
(This procedure can also be used for virtually any material that must be pelleted prior to fixation and thin sectioning)Primary fix:2% glutaraldehyde (from 25% or 10% stock) in microtubule assembly buffer.For better contrast of the tubulin, you can add 0.1-.5% tannic acid.Secondary Fix:0.5-1% OsO4 in the same buffer. OsO4 is kept in the refrigerator in a jar and is made as a 4% solution in water. It is very......阅读全文

透射电子显微镜(Transmission-electron-microscopy,-TEM)
透射电镜具有很高的空间分辩能力,特别适合纳米粉体材料的分析。其特点是样品使用量少,不仅可以获得样品的形貌,颗粒大小,分布以还可以获得特定区域的元素组成及物相结构信息。透射电镜比较适合纳米粉体样品的形貌分析,但颗粒大小应小于300nm,否则电子束就不能透过了。对块体样品的分析,透射电镜一般需要对样品进
