Drug Manufacturing Process Validation Service | Cryo-EM
In modern pharmaceutical development, ensuring the consistency, integrity, and reproducibility of drug manufacturing processes is essential for regulatory approval and product quality assurance. In the production of complex biologics, gene therapies, and vaccine vectors, cryogenic electron microscopy (Cryo-EM) offers critical structural information under near-native conditions. By revealing detailed morphological and structural information, Cryo-EM provides actionable insights that support process optimization, method validation, and final product quality assurance.
MtoZ Biolabs offers a dedicated Drug Manufacturing Process Validation Service utilizing Cryo-EM technology, helping pharmaceutical and biotechnology companies strengthen process control, support regulatory submissions, and accelerate the development of high-quality therapeutic products.
Service at MtoZ Biolabs
MtoZ Biolabs' Cryo-EM-based Drug Manufacturing Process Validation Service enables direct imaging of pharmaceutical particles, aggregates, nanoparticles, and macromolecular assemblies under near-native conditions. Our services include:
✔️Morphological Assessment: Visualization of particle size, shape, lamellarity, and surface features without artifacts.
✔️Aggregate and Impurity Detection: Identification and quantification of subvisible aggregates or contaminants at nanoscale resolution.
✔️Encapsulation and Loading Validation: Structural verification of payload encapsulation efficiency and uniformity.
✔️Batch-to-Batch Comparability: Quantitative comparison of structural attributes across production batches.
✔️Stability Monitoring: Assessment of structural changes under storage, stress, or formulation modification conditions.
These insights are crucial for confirming that manufacturing processes consistently produce products meeting predefined specifications.
