A note about centrifugation: g (1 x gravity) represents relative centrifugal force (RCF), but the recommended centrifugation speed is often listed in protocols as revolutions per minute (RPM). RCF is dependent on the length of the radius of the rotor, thus the same RPM may not generate the same g force in another centrifuge.
