There are several types of pelleting, each suited for different applications: - Differential Centrifugation: Separates cellular components based on size and density by using progressively increasing centrifugal forces. - Density Gradient Centrifugation: Involves layering the sample on a density gradient medium, such as sucrose or Percoll, to separate particles based on buoyant density. - Zonal Centrifugation: Particles are separated into zones based on their size and shape as they move through a gradient medium.
