Polysomes are harvested from the postmitochondrial extract by centrifuging at 125,000 g max in a swinging bucket rotor [such as a Beckman (Fullerton, CA) SW41 or Sorvall (Newtown, CT) T-641] for 60 min at 4°. The “cytosolic” supernatant obtained in this step should also be saved and assayed for endonuclease activity. Gently resuspend the …
