Analytical Ultracentrifuge
For Advanced Macromolecule Characterization
Analytical Ultracentrifugation can measure:
- Molecular weight and molecular size
- Protein aggregation and heterogeneity
- Particle size distribution
- Biomolecular interactions
- Sedimentation coefficients
- Viral vector characterization
- Nanoparticles loading states
- Nanoparticle and macromolecule stability
- Sample purity and solution behavior
Analytical ultracentrifugation (AUC) is a powerful and highly accurate technique used to characterize proteins, antibodies, viral vectors, nanoparticles, and other macromolecules directly in solution. Unlike many analytical methods, AUC measures molecular properties without requiring immobilization, labeling, or matrix interactions, helping researchers generate highly reliable data under near-native conditions.
Analytical ultracentrifuges provide critical insights into molecular weight, size distribution, shape, aggregation behavior, sedimentation properties, and intermolecular interactions. These capabilities make AUC a valuable tool for biopharmaceutical development, protein characterization, gene therapy research, and quality assessment workflows.
The Beckman Coulter Life Sciences Optima AUC Ultracentrifuge supports both sedimentation velocity and sedimentation equilibrium experiments, density gradient experiments, and analytical band centrifugation experiments, enabling comprehensive characterization of complex biomolecular samples with exceptional sensitivity and reproducibility.
FAQ on Analytical Ultracentrifuges
What is the difference between analytical and preparative ultracentrifugation?
Preparative ultracentrifugation is primarily used to separate and isolate particles for collection, while analytical ultracentrifugation is used to characterize and measure molecular properties. Analytical systems provide quantitative information about molecular weight, sedimentation behavior, aggregation, and sample heterogeneity.
What is analytical ultracentrifugation?
Analytical ultracentrifugation (AUC) is a solution-based analytical technique that uses high centrifugal forces to study the physical properties of macromolecules and particles. Researchers use AUC to determine molecular weight, size distribution, shape, aggregation state, and molecular interactions without the need for labels or reference standards.
What are the applications of analytical ultracentrifugation?
Analytical ultracentrifugation is widely used in biopharmaceutical development, protein analysis, antibody characterization, viral vector research, nanoparticle studies, and formulation development. It is particularly valuable for studying biomolecules under conditions that closely resemble their native environment.
How does analytical ultracentrifugation work?
Analytical ultracentrifugation works by spinning samples at very high speeds and monitoring how molecules move through a solution. The rate of sedimentation is measured using optical detection systems, allowing researchers to characterize molecular size, shape, concentration, and interaction behavior with high precision.
