Comprehensive Cryo-EM Services: From Sample Preparation to High-Resolution Imaging

In the world of structural biology, achieving high-resolution imaging of biomolecules is crucial for understanding their function and interactions. Cryo-Electron Microscopy (Cryo-EM) has revolutionized the field, enabling scientists to visualize the 3D structure of proteins, viruses, and other biological macromolecules in unprecedented detail. However, achieving optimal results with Cryo-EM is no easy feat. The process requires specialized expertise, state-of-the-art equipment, and careful attention to detail from sample preparation to data analysis.

At Shuimu, we are proud to offer comprehensive Cryo-EM services that cover every step of the process—from sample preparation to high-resolution imaging and data analysis. Whether you're a researcher exploring novel drug targets, a biotech company developing vaccines, or a laboratory studying complex protein assemblies, our team is here to support your scientific endeavors with cutting-edge technology and world-class expertise.

What is Cryo-EM?

Cryo-Electron Microscopy is a powerful technique that allows researchers to observe biomolecules at near-atomic resolution without the need for crystallization. Unlike traditional electron microscopy, which requires samples to be placed in a vacuum and prepared on solid supports, Cryo-EM involves rapidly freezing samples in vitreous ice, preserving their natural structure. This technique enables the visualization of biological samples in their native state, allowing for more accurate insights into their molecular architecture.

Step 1: Sample Preparation

The first and arguably most critical step in Cryo-EM is sample preparation. At Shuimu, we understand that high-quality data starts with high-quality samples. Our team of experts uses advanced techniques to prepare your samples to the highest standards, ensuring they remain stable and intact during imaging.

Our comprehensive sample preparation services include:

• Vitrification: We use state-of-the-art plunge-freezing techniques to rapidly cool your sample in liquid ethane, preserving the biomolecules in their native, hydrated state.
• Cryo-Plunger and Grid Optimization: Our cutting-edge cryo-plungers allow for controlled and precise vitrification, while our optimized grids ensure that your sample is properly supported for imaging.
• Sample Cleanup and Concentration: We can assist with concentration, purification, and buffer exchange, ensuring that the sample is in the optimal condition for Cryo-EM analysis.

Step 2: Cryo-EM Imaging

Once your samples are prepared, the next step is high-resolution imaging. At Shuimu, we use some of the most advanced Cryo-EM microscopes available to ensure you get the highest quality data possible.

Our facility is equipped with top-of-the-line cryo-transmission electron microscopes (Cryo-TEM), capable of capturing high-resolution images of biomolecules. With state-of-the-art detectors and the latest in electron microscopy technology, we can visualize your samples in their native, hydrated state with minimal distortion or damage.

• Single-Particle Analysis (SPA): Ideal for proteins, protein complexes, and other macromolecules, SPA allows for the reconstruction of 3D structures from thousands of 2D images, producing high-resolution models of the molecules.
• Tomography: For larger samples, such as cells or virus particles, Cryo-EM tomography enables the 3D reconstruction of whole cells or virus assemblies, providing unparalleled insights into cellular and viral structures.
• Cryo-ET: Our cryo-electron tomography (Cryo-ET) service can provide 3D reconstructions at even higher resolution, allowing for the study of macromolecular interactions in their natural cellular environment.

Step 3: Data Analysis and Interpretation

Obtaining high-resolution images is only part of the process—interpreting the data is equally critical. Our experienced team at Shuimu provides in-depth analysis of your Cryo-EM data, including refinement, map interpretation, and structural modeling. We employ advanced software tools to process the data, and our team works closely with you to extract meaningful biological insights.

Our data analysis services include:

• 3D Reconstruction: We process Cryo-EM data to generate accurate 3D reconstructions of your biomolecules, allowing you to visualize their atomic structure in high detail.
• Model Building: Using cryo-EM maps, we can build atomic models of your molecule, providing insights into its functional mechanisms and potential drug-binding sites.
• Quality Assessment: We conduct rigorous assessments of map quality, ensuring that your results meet the highest standards of accuracy and resolution.
