Optimizing centrifugation of coagulation samples in ...

Background: High acceleration centrifugation conditions are used in laboratory automation systems to reduce the turnaround time (TAT) of clinical chemistry samples, but not of coagulation samples. This often requires separate sample flows. The CLSI guideline and manufacturers recommendations for coagulation assays aim at reducing platelet counts.

Collect the cells by centrifugation (300 g for 3 min). Wash the cells once with PBS and centrifuge, as above. Discard the supernatant and resuspend with 5 volumes of extraction buffer. The cellular suspension is homogenized with a Teflon-glass homogenizer with 10–20 up-and-down passes of the pestle.

Isolation of mitochondria from cells and tissues

Isolation of mitochondria from cells and tissues

Most methods to isolate mitochondria rely on differential centrifugation, a two-step centrifugation carried out at low speed to remove intact cells, cell and tissue debris, and nuclei from whole cell extracts followed by high speed centrifugation to concentrate mitochondria and separate them from other organelles.

Centrifuge Science project

The purpose of this experiment is to find out whether certain liquids are comprised of a liquid and a dissolved solid or two different liquids of different densities. Spinning a liquid in a centrifuge will separate materials of different densities from each other but will not be able to separate out materials that have been chemically bonded into the liquid suspension.
