The immediate and broad application of this new tool was complicated by the overwhelming prob lems inherent in specimen preparation for the investigation of cellular struc tures. The microtechniques applied in light microscopy were no longer appli cable, since even the thinnest paraffin layers could not be penetrated by electrons. Many competent biological and medical research workers expressed their anxiety that objects in high vacuum would be modified due to complete dehydration and the absorbed electron energy would eventually cause degrada tion to rudimentary carbon backbones. It also seemed questionable as to whether it would be possible to prepare thin sections of approximately 0. 5 11m from heterogeneous biological specimens. Thus one was suddenly in posses sion of a completely unique instrument which, when compared with the light microscope, allowed a 10-100-fold higher resolutio | | 出版日期 | Book 1987 | | 关键词 | Thin section; antibody; cell; cell culture; electron microscopy; electron optics; microscopy; nucleic acid; | | 版次 | 1 | | doi | https://doi.org/10.1007/978-3-642-48848-1 | | isbn_softcover | 978-3-540-17592-6 | | isbn_ebook | 978-3-642-48848-1 | | copyright | Springer-Verlag Berlin Heidelberg 1987 |
