Protein Folding & Higher Order Structure Analysis Services
In the biopharmaceutical industry, a protein's three-dimensional conformation—its Higher Order Structure (HOS)—is inextricably linked to its biological function. Even the slightest structural variation or misfolding can trigger immunogenic responses, reduce drug efficacy, or even derail an entire R&D program.
Creative Diagnostics provides in-depth, highly accurate protein folding and HOS evaluation services. By comprehensively confirming the conformational state of your proteins, we help you verify both their biological activity and physical stability. We understand that correct protein folding is absolutely critical for the proper function and long-term performance of biotherapeutics. Our analytical platform delivers robust data to support your developability assessments, formulation development, and quality control (QC) efforts.
Our Services
To meet the rigorous demands of different R&D stages, we have built a multidimensional biophysical characterization platform. Using a flexible combination of methods across various structural levels, we provide a complete spatial profile of your protein samples:
- Secondary Structure & Global Folding Assessment: Rapidly and sensitively detect the backbone features and overall folding state of your protein. We help you confirm that your drug candidate possesses the correct functional conformation and establish reliable baseline profiles to strictly monitor batch-to-batch consistency during large-scale manufacturing.
- Dynamic Monitoring of Thermodynamic & Physical Stability: Track conformational changes in real-time under environmental stress in native (label-free) conditions. By accurately measuring key stability metrics (such as melting thresholds and aggregation onset points), we provide deep insights into your sample's physicochemical stability, guiding and accelerating your formulation screening.
- High-Resolution 3D Conformation Analysis: For projects that require a deep dive into mechanisms of action, we offer complete analysis—from capturing spatial conformations to high-resolution 3D model reconstruction. By visualizing the fine topological structures of the protein's interior and surface at the atomic level, we lay a solid foundation for Structure-Based Drug Design (SBDD) and subsequent engineering.
Our Advantages
- Minimal Sample Consumption: Utilizing advanced micro-volume detection platforms, we can capture high-precision data using only microliters of low-concentration, precious sample matter, maximizing your R&D budget.
- High Throughput & Fast Turnaround: Our optimized workflows support high-throughput matrix screening, significantly reducing testing cycles and accelerating your formulation screening and candidate evaluation process.
- Native-State Non-Destructive Testing: No need to introduce exogenous fluorescent dyes or perform complex sample preparation. This ensures the HOS and stability data we collect truly reflect the protein's natural state in physiological environments or actual formulation conditions.
- Deep Data Insights: Our team of structural biology experts delivers more than just raw spectral data. You will receive a comprehensive evaluation report featuring in-depth mechanistic analysis, multidimensional conformational comparisons, and actionable optimization advice.
Workflow
We analyze your protein's unique characteristics and core needs (e.g., comparability studies, forced degradation analysis) to design the most suitable HOS characterization plan.
We rapidly establish the optimal buffer system, sample concentration, and instrument parameters for your specific sample.
Using a suite of complementary biophysical techniques, we perform comprehensive, parallel cross-testing in strict accordance with Standard Operating Procedures (SOPs).
Utilizing specialized software for data fitting and spectral analysis, we deliver a detailed report containing methodology, core structural parameters, stability metrics, and clear scientific conclusions.
Applications
- Biosimilar Comparability Studies: Rigorous statistical comparison of the folding state and HOS between candidate drugs and originator biologics.
- Biologics Formulation Development: High-throughput screening of optimal buffer types, pH levels, and stabilizing excipients to significantly enhance formulation stability.
- Forced Degradation Studies: Evaluating protein unfolding and irreversible aggregation behaviors under environmental stressors like heat, pH extremes, light exposure, and mechanical shear stress.
- Developability Assessment & Lead Optimization: Uncovering the conformational evolution and binding modes of target proteins interacting with ligands.
