What spin speeds should I use to isolate the plasma prior to using a cell-free DNA extraction kit?

We recommend using a two-step centrifugation process to isolate the plasma.

An initial spin speed of 2,000 g for 10 minutes to isolate the plasma fraction from the red and white blood cells, then a second high spin of minimum speed 10,000 g for 10 minutes, to pellet and remove intact cells and cellular debris from the plasma fraction.
