Key Services Contributing to Cryo-EM Costs

The overall cost of Cryo-EM is influenced by the specific services required for a project. The manual outlines several distinct service categories, each representing a potential line item in your research budget.

1. Cryo-EM Structure Determination (Single Particle Analysis - SPA): Single Particle Analysis is described as a powerful approach integrating Cryo-EM to determine high-resolution 3D structures of biological macromolecules like proteins and viruses. The workflow involves collecting extensive 2D images and using computational algorithms for processing and reconstruction. The service handles various samples including Antigen-antibody complexes, small molecules & targets, PROTACs, membrane proteins (GPCRs, ion channels, transporters), VLPs, and peptides. The process, from project consultation and feasibility evaluation to data collection, 3D reconstruction, and model refinement, involves significant resources, including cutting-edge equipment, elite scientist teams, and extensive experience. Shuimu emphasizes an uncompromising pursuit of resolution, achieving resolutions as high as 1.8 Å and down to 1.4 Å. Higher required resolutions often necessitate more extensive data collection and processing, impacting the overall project cost. Shuimu offers a complimentary project feasibility assessment, which is valuable for initial budget planning as it helps evaluate the likelihood of success before committing significant resources.

2. Protein Preparation and Analysis Services: High-quality protein samples are fundamental for successful Cryo-EM. Shuimu offers comprehensive services for protein expression, purification, and analysis.

o Protein Expression Systems: Various systems are available, including E. coli, mammalian cells, insect cells, and cell-free systems. Each system has different characteristics affecting yield, post-translational modifications, and suitability for different protein types, which in turn impacts the complexity and cost of expression. For example, E. coli is economical and fast but may result in inclusion bodies and lacks post-translational modifications, while mammalian cell systems are higher cost but produce proteins closest to their natural state.

o Protein Purification Processes: Methods like Affinity chromatography, ion-exchange chromatography, gel filtration, and RP-HPLC are used to achieve high purity. The complexity of purification depends on the protein and chosen expression system, directly influencing labor and material costs.

o Protein Quality Control (QC) & Analysis: Assays such as SDS-PAGE, Western blot, mass spectrometry, thermal stability, and solubility testing, along with binding analysis using SPR, BLI, and ELISA, are crucial for ensuring sample quality before Cryo-EM. These QC steps are vital for budget planning as they help avoid wasting expensive Cryo-EM instrument time on poor samples. However, performing these assays adds to the overall cost of protein preparation. Sample submission requirements for protein solutions specify concentration (≥ 2mg/mL), volume (≥ 100ul), and purity (≥90%), highlighting the importance of pre-existing quality. Requirements for buffer solutions, small molecules, and their affinity data with target proteins are also specified. Meeting these initial quality benchmarks is essential for efficient budgeting.

3. Instrument Access: Direct access to Cryo-EM instruments is a major component of the Cryo-EM cost. Shuimu offers 24-hour instrument time for 300 kV data acquisition. They have 8 electron microscopes in Beijing (the source is slightly conflicting on the number, mentioning 2 x 300 kV and later 12 instruments in Beijing, but consistently lists 6 in Hangzhou). Machine time is reserved by the day. The cost is essentially tied to the duration of instrument usage. Shuimu highlights features designed to optimize this cost:

o AI-driven platforms and SMART software reduce machine runtime and required data volume, improving overall efficiency.

o Professional quality service includes daily platform maintenance, ensuring equipment is always in optimal condition and guaranteeing efficiency and quality of data collection.

o High instrument availability (>330 days/year) and low fault rates (>97% annual fault-free operation) mean less time wasted due to technical issues, helping adhere to the planned budget.

4. Specialized Cryo-EM Techniques: Certain projects may require specialized techniques that have their own cost structures.

o Negative Staining: This is a lower-resolution technique used for initial assessment of particle homogeneity, size, morphology, etc.. It's explicitly mentioned as being available at a lower cost than full Cryo-EM. It can be a cost-effective first step in budget planning to quickly assess sample quality before proceeding to more expensive Cryo-EM data collection. Sample requirements for negative staining include high protein purity (>95%), specific volume and concentration, and buffer restrictions.

o Cryo Characterization: This service uses ultra-low temperature technology for observing specific particles like AAV, liposomes, LNPs, and VLPs. It leverages the self-developed NanoSMART AI system for automatic identification and analysis. This is a dedicated service offering detailed reports on size distribution, roundness, and integrity, representing a distinct cost for characterization projects involving these particle types. Sample submission requirements are specific to the particle type, e.g., concentration suggestions for liposomes, viruses (AAV), and LNPs.

o MicroED Solutions: Micro-electron diffraction is used for resolving high-resolution structures of microcrystals and nanocrystals, particularly small molecule drugs, peptides, and protein crystals. Shuimu utilizes its proprietary eTasED software for this. This is a specialized technique for specific sample types (crystals) and adds another option to consider in the budget for small molecule or peptide structural analysis. Shuimu reports high success rates (>80%) and achieved resolutions of 0.6~1.0Å for MicroED projects.

o GraFuture™ Grids: These graphene support grids are designed to overcome challenges like severe preferred orientation, high background noise, and issues with small molecular weight or low concentration samples, which can otherwise hinder successful Cryo-EM data collection. While likely adding to material cost, using GraFuture™ grids (GO or RGO) for challenging samples can potentially save significant downstream costs by improving data quality and reducing the need for repeated experiments or extensive optimization. This is an example of how investing slightly more in sample preparation materials can be a cost-effective strategy in budget planning for difficult targets.

5. Crystallography: While Cryo-EM is a primary focus, Shuimu also offers One-Stop Crystallographic Analysis. This technique, using X-ray crystallography, resolves high-resolution structures and is particularly highlighted for antigen-antibody complexes. Crystallography is an alternative structural biology method with its own set of steps (expression, purification, crystallization, data collection, analysis) and associated costs. Sample requirements for crystallization differ from Cryo-EM (higher purity and concentration generally needed). Including this in a project involves a separate budget consideration.

6. Antibody Discovery and Characterization Assays: For drug development projects, antibody discovery and analysis services are offered. This involves a multi-stage workflow including material preparation, antibody generation (panning and screening), and antibody expression, purification, and characterization. Characterization often employs techniques like ELISA, SPR, and BLI to assess binding activity, affinity, and kinetics. Each stage and assay contributes to the overall project cost. For instance, SPR and BLI are used for detailed molecular interaction analysis, while ELISA is used for detecting target protein content. Sample submission requirements for these assays specify purity, concentration, volume, and buffer conditions, which must be factored into the sample preparation budget. These services represent a significant portion of the budget for antibody-focused research.

Factors Influencing Cryo-EM Cost and Budget Planning

Based on the services and requirements described, several key factors directly influence the final Cryo-EM cost and must be considered during budget planning:

· Sample Type and Quality: The inherent complexity of the sample (e.g., membrane protein vs. soluble protein, small protein vs. large complex, virus particle) and whether it meets purity, concentration, volume, and buffer requirements are major cost drivers. Poor sample quality necessitates more extensive optimization, potentially leading to increased preparation costs and wasted instrument time.

· Need for Protein Production: If Shuimu needs to handle protein expression and purification from gene sequence, this adds significant steps and costs compared to a client providing ready-to-go purified sample. The choice of expression system greatly impacts this cost.

· Project Scope and Required Services: A full SPA structure determination project will naturally be more expensive than a negative staining QC check. Projects requiring multiple services (e.g., protein expression + purification + SPA + SPR assay) will have a higher overall cost than a single-service project.

· Sample Difficulty and Optimization: Challenging samples (e.g., prone to preferential orientation, low stability, low concentration) may require more extensive grid screening, optimization, and potentially specialized materials like GraFuture™ grids, increasing instrument time and material costs.

· Required Resolution and Data Volume: Achieving higher resolutions requires collecting and processing larger volumes of data, increasing instrument time and computational resources, thus adding to the cost.

· Instrument Time Efficiency: While instrument time is a direct cost, the efficiency of data collection, influenced by sample quality, grid preparation, instrument performance, and AI software, directly impacts how much usable data is acquired per paid hour/day, affecting the effective cost.

· Data Analysis and Modeling Needs: Computational resources and expert time for data processing, 3D reconstruction, and model refinement are significant components of the overall Cryo-EM cost.
