Study Notes
Centrifugation Basics
- The primary purpose of centrifugation is to separate particles of different sizes, densities, or shapes based on their sedimentation rates.
- Centrifugation utilizes the force of centrifugal force, which pushes particles away from the axis of rotation, to separate particles.
Applications in Research
- The field of biology extensively applies centrifugation as a research technique to separate and analyze biological samples, such as cells, proteins, and nucleic acids.
Differential Centrifugation
- The purpose of differential centrifugation is to separate particles of different sizes and densities by spinning them at different speeds, resulting in distinct layers or pellets.
Preparation of Biological Samples
- Centrifugation is relevant to the preparation of biological samples as it allows for the separation of particles, such as cells and debris, and the concentration of target molecules, making it easier to analyze and study them.
