Cryo-EM for Subcellular Organelles

Inquiry

The rapid development of cryogenic electron microscopy (cryo-EM) in the structural determination field suggests that the structural analysis of molecular components in entire cells and subcellular organelles is about to enter a new era. The electron tomography technology can be used to study the internal structure of subcellular organelles with a certain thickness in the natural state. Our cryo-EM platform is constantly learning to identify sub-organelles more accurately, and we continue to make breakthroughs in cytoskeleton, nuclear pore complex, and other sub-organelles.

Cryo-Electron Tomography (Cryo-ET), one of the techniques of Cryo-EM, is used to produce three-dimensional (3D) pictures from a series of tilted Cryo-EM images. Cryo-ET has gained more and more attention in the field of Cryo-EM in the recent years, which can be applied to study the internal organisms, typically for many structures inside cells, for example, subcellular organelles. Organelle is a specialized subunit within a cell, which contains cytoskeleton, mitochondria, endoplasmic reticulum, flagellum and so on. Cryo-EM allows to study the high-resolution structures of macromolecules, and Cryo-ET provides the information about cellular processes. With the combination of 3D imaging and specimen preparation that preserves the integrity of the cell structure, Cryo-ET can observe the internal structure of cell with high resolution.

Cryo-EM for Subcellular Organelles

At Creative Biostructure, we have the most advanced Electron Microscopes equipment and software. In addition, Creative Biostructure has a professional team for experimental design of subcellular organelles separation and Cryo-ET data analysis.

The advantages of our service include:

  1. The most advanced direct-electron detectors and image processing software;
  2. Allow near-atomic resolution structures to be calculated without crystallization and only need a small amount of purified samples;
  3. Provide the unique possibility to image organelle in their native environment or in situ;
  4. Visualize the interaction of proteins and cells, capture transient and dynamic processes;
  5. Bring a hope for further understanding of life mechanisms and mysteries.

Our cryo-EM team is very happy to provide cryo-EM structure analysis services for subcellular organelle samples. If you are interested in our services, please feel free to contact us. We are looking forward to cooperating with you.
