'''Differential Centrifugation''' is a common procedure in [[microbiology]] and [[biochemistry]], which is used to separate and isolate [[cell]] components and [[organelles]]. This process is based on the principle of [[sedimentation]] of particles in a [[centrifuge]].

== Overview ==

Differential centrifugation involves a series of centrifugation steps, where the speed and duration of centrifugation are varied to separate cellular components according to their size, shape, and density. The process begins with a low-speed centrifugation to pellet the largest particles, such as whole cells and nuclei. The supernatant is then subjected to a higher speed centrifugation to pellet the next largest particles, such as mitochondria. This process is repeated with increasing speeds until all desired components are separated.

== Process ==

The process of differential centrifugation involves the following steps:

# '''Homogenization''': The cells are first broken up to release their contents. This can be done mechanically or chemically.
# '''Low-speed centrifugation''': The homogenate is centrifuged at a low speed to pellet the largest particles, such as whole cells and nuclei.
# '''Intermediate-speed centrifugation''': The supernatant from the previous step is centrifuged at a higher speed to pellet the next largest particles, such as mitochondria.
# '''High-speed centrifugation''': The supernatant from the previous step is centrifuged at an even higher speed to pellet smaller particles, such as lysosomes and peroxisomes.
# '''Ultracentrifugation''': The supernatant from the previous step is centrifuged at the highest speed to pellet the smallest particles, such as ribosomes and viruses.

== Applications ==

Differential centrifugation is widely used in the field of [[cell biology]] to isolate specific cell components for further analysis. It is also used in the field of [[virology]] to concentrate viruses from a dilute solution.
