Centrifugation In Biotechnology

After centrifugation, all the cell debris has been forced to the bottom of the PCR tube (1), leaving only the DNA in the liquid supernatant (2). The supernatant should look clear, like water. Finally, you will transfer the supernatant into a new PCR using the micropipette. Set the micropipette to 20μL and put on a new tip.

Apr 01, 2010 Following centrifugation, the aqueous phase containing the purified DNA can be transferred to a clean tube for analysis. DNA can also be recovered and concentrated from the aqueous phase by ethanol precipitation or through the use of a centrifugal filter unit ... (Peqlab Biotechnology, Erlangen, Germany).

Cell biology is an exciting and dynamic area that helps discover the fascinating world of cells. It includes the study of the structure and organization, growth, regulation, movements and interaction of the cells. Cell biology is closely related to other areas of biology such as genetics, molecular biology, and biochemistry.

Centrifugal force is the apparent outward force on a mass when it is rotated. Since Earth rotates around a fixed axis, the direction of centrifugal force is always outward away from the axis, opposite to the direction of gravity at the equator; at Earth’s poles it is zero. (Centripetal force is the necessary inward force that keeps the mass from moving in a straight line; it is the same …

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.

Jun 23, 2015 Centrifugation is a process which involves the use of the centrifugal force for the sedimentation of heterogeneous mixtures with a centrifuge, used in industry and in laboratory settings. This process is used to separate two immiscible liquids. More-dense components of the mixture migrate away from the axis of the centrifuge, while less- dense ...

The goal of disinfection of public water supplies is the elimination of the pathogens that are responsible for waterborne diseases. The transmission of diseases such as typhoid and paratyphoid fevers, cholera, salmonellosis, and shigellosis can be controlled with treatments that substantially reduce the total number of viable microorganisms in the water.
