About
Structura Biotechnology is the company behind CryoSPARC™, a powerful end-to-end software platform for single-particle cryo-electron microscopy (cryo-EM) — a Nobel Prize-winning technique for determining the 3D atomic structures of proteins and biological molecules in near-native states. CryoSPARC combines cutting-edge reconstruction algorithms with an intuitive workflow, handling every stage from motion correction to atomic-resolution structure determination. It excels with challenging targets including membrane proteins, GPCRs, ion channels, and flexible or heterogeneous complexes. The platform also includes CryoSPARC Live™, which delivers real-time data processing, quality assessment, and feedback during microscope data collection, enabling researchers to make immediate decisions and optimize sessions on the fly. In collaboration with Thermo Fisher Scientific, Structura also offers Embedded CryoSPARC Live, integrated directly into Thermo Scientific cryo-TEM hardware systems for a seamless lab-to-structure pipeline. Trusted by researchers worldwide, CryoSPARC is the de facto standard for cryo-EM software in both academic institutions and pharmaceutical companies. It is particularly valuable in drug discovery, enabling structure-based drug design by revealing how drug candidates interact with target proteins at atomic resolution. The platform accelerates research timelines from weeks to days, making high-throughput structural biology a reality.

Cons
- Highly Specialized Use Case: CryoSPARC is purpose-built for cryo-EM structural biology, making it irrelevant outside of life science research and drug discovery contexts.
- Requires Significant Computing Infrastructure: Processing cryo-EM datasets demands high-performance computing resources (GPU clusters, large RAM), creating a significant infrastructure barrier for smaller labs.
- Commercial Licensing Costs: While free for academic and non-commercial use, pharmaceutical and biotech companies require a commercial license, which can represent a substantial cost.
Frequently Asked Questions
What is CryoSPARC?
CryoSPARC (Cryo-EM Single Particle Ab-Initio Reconstruction and Classification) is Structura Biotechnology's flagship software platform for analyzing cryo-electron microscopy data and determining 3D atomic structures of proteins and biological molecules.
What is cryo-EM and why is it important?
Cryo-electron microscopy (cryo-EM) is a Nobel Prize-winning imaging technique where biological samples are frozen in thin ice and imaged with an electron microscope. The resulting images are computationally analyzed to reconstruct 3D atomic structures, revealing how proteins function and interact — critical for drug discovery and basic research.
Is CryoSPARC free to use?
CryoSPARC is available free of charge for academic and non-commercial research use. Commercial use by pharmaceutical, biotech, and for-profit organizations requires a commercial license from Structura Biotechnology.
What is CryoSPARC Live and how does it differ from CryoSPARC?
CryoSPARC Live is an extension that enables real-time data processing and quality assessment during active microscope data collection sessions. Unlike the standard CryoSPARC platform (used for post-collection analysis), CryoSPARC Live allows researchers to monitor results and make optimization decisions on the fly, reducing wasted microscope time.
What types of biological samples can CryoSPARC analyze?
CryoSPARC is designed to handle a wide range of biological targets, including globular proteins, protein-ligand complexes, membrane proteins, GPCRs, ion channels, and flexible or heterogeneous macromolecular complexes — including many challenging sample types that are central targets in drug discovery.
