분석형 초고속원심분리기 로터
분석형 초고속원심분리기(AUC) 로터는 회전하는 샘플에 빛이 투과된다는 점에서 특별합니다. AUC의 광학 시스템(UV-Vis 흡광도 및 레일리(Rayleigh) 간섭)은 침전이 진행되는 분자의 용액 움직임을 관찰합니다.
분석형 초고속원심분리기 로터는 Optima AUC 또는 ProteomeLab XL-A/I에만 사용됩니다.
FAQ on Analytical Ultracentrifuge Rotors
What is analytical ultracentrifugation (AUC)?
Analytical ultracentrifugation (AUC) is a technique that combines high-speed centrifugation with optical detection to study the behavior of molecules in solution. Researchers use AUC to characterize biomolecules, determine molecular weight, and analyze molecular interactions without modifying the sample.
Learn MoreWhat applications is analytical ultracentrifugation used for?
Analytical ultracentrifugation is commonly used for protein characterization, molecular weight determination, aggregation analysis, biologics development, viral vector characterization and studies of macromolecular interactions.
How does analytical ultracentrifugation work?
In analytical ultracentrifugation, samples are subjected to high centrifugal forces while optical systems continuously monitor molecular movement during sedimentation. The resulting data can be used to evaluate molecular size shape, heterogeneity, and interactions.
What is sedimentation equilibrium (SE-AUC)?
Sedimentation equilibrium is an AUC technique in which sedimentation is balanced by diffusion until equilibrium is reached. Researchers commonly use SE-AUC to determine molecular weight and study molecular association behavior in solution.
Why is analytical ultracentrifugation used for protein characterization?
AUC enables proteins to be analyzed in their native solution state without labeling or immobilization. This provides information about molecular weight, oligomerization, aggregation and sample heterogeneity that can be difficult to obtain using other analytical techniques.
What is sedimentation velocity (SV-AUC)?
Sedimentation velocity analytical ultracentrifugation measures how quickly particles move through solution when exposed to centrifugal force. SV-AUC is commonly used to assess size distributions, aggregation levels, sample purity and molecular interactions.
What is the difference between analytical and preparative ultracentrifugation?
Preparative ultracentrifugation is used to isolate, purify or concentrate biological materials. Analytical ultracentrifugation is used to characterize molecules and study their physical properties in solution. Rather than recovering material, AUC generates data that provide insights into molecular behavior and interactions.
