Cryo-electron tomography aims to act as an interface between in vivo cell imaging and techniques achieving atomic resolution. This attempt to bridge the resolution gap is facilitated by recent software and hardware advances. Information provided by atomically resolved macromolecules and molecular interaction data need to be put into a common framework in order to create a hybrid multidimensional cellular image. A major partner in this enterprise is the development of regularization and pattern recognition techniques, which try to identify macromolecular complexes as a function of their structural signature in cryo-electron tomograms of living cells.
冷冻电子断层扫描旨在充当体内细胞成像与实现原子分辨率技术之间的桥梁。近期软硬件的进步推动了弥合分辨率差距的这一尝试。由原子分辨率的大分子提供的信息和分子相互作用数据需要被置于一个通用框架中,以便创建一个混合多维细胞图像。这项工作的一个主要伙伴是正则化和模式识别技术的发展,这些技术试图在活细胞的冷冻电子断层扫描图中根据其结构特征识别大分子复合物。
