Centrifugation - Wikipedia

Centrifugation - Wikipedia

Centrifugation is a mechanical process which involves the use of the centrifugal force to separate particles from a solution according to their size, shape, density, medium viscosity and rotor speed. The denser components of the mixture migrate away from the axis of the centrifuge, while the less dense components of the mixture migrate towards the axis.

May 14, 1998 Of the DNA extraction methods tested, sonication did not produce high molecular weight DNA while the differential centrifugation method generated a DNA pool dominated by bacterial DNA and therefore not suitable for analysis of eukaryotes. Neither of these methods fulfilled all requirements for a suitable DNA extraction method.

The second reagent dissolves plasma, mitochondria and ER-golgi membranes but does not solubilize the nuclear membranes. After recovering intact nuclei by centrifugation, a third reagent yields the soluble nuclear extract. An additional nuclear extraction with micrococcal nuclease is performed to release chromatin-bound nuclear proteins.

Purification of RNA using TRIzol (TRI reagent)

Purification of RNA using TRIzol (TRI reagent)

Therefore, RNA, DNA, and protein can be purified from a single sample (hence, the name TRIzol). TRIzol extraction is also an effective method for isolating small RNAs, such as microRNAs, piwi-associated RNAs, or endogeneous, small interfering RNAs. However, TRIzol is expensive and RNA pellets can be difficult to resuspend.
