Centrifugation

Motile sperm were isolated by Percoll centrifugation, the total RNA extracted and verified using sperm-specific RT-PCR. ❋ Unknown (2010)

“Was the RNA degraded in the centrifugation step?” ❋ Siddhartha Mukherjee (2010)

I'm in the midst of a 3.5 hour centrifugation, so I figured I might as well do follow up on her tag. ❋ Amanda (2008)

The bacterial culture is concentrated by centrifugation and disrupted by lysis with an alkaline detergent solution containing enzymes to degrade contaminating RNA. ❋ Unknown (2005)

Alcohol (isopropanol) precipitation concentrates the eluted plasmid DNA, which is collected by centrifugation, washed, and redissolved in buffer. ❋ Unknown (2005)

For many years, the method of choice for supercoiled plasmid and virus DNA purification was cesium chloride density gradient centrifugation in the presence of an intercalation agent (such as ethidium bromide or propidium iodide). ❋ Unknown (2005)

Recently, simplified ion-exchange column chromatography methods (commonly termed a mini-prep) have largely supplanted the cumbersome and time-consuming centrifugation protocol to yield large quantities of endotoxin-free plasmid DNA in a relatively short period of time. ❋ Unknown (2005)

Had he done so he would have heard Pawelczyk talk about centrifugation and countermeasure research needed in that area. ❋ Unknown (2006)

UNFILTERED: A wine that has been bottled without exposure to any type of centrifugation, cold stabilization, or filtration through membrane or cellulose pad filters is said to be an unfiltered wine. ❋ Jr. Robert M. Parker (2005)
