Repeat the centrifugation step as needed to ensure the complete precipitation of protein. Carefully decant or pipette the supernatant from the pellet. 6. For this example the protein of interest remains in the supernatant from step 5 (35% saturation) and a second precipitation step at 70% saturation is required to pellet the protein of interest.

The supernatant contains RNA and protein. If the sample had a high fat content, there will be a layer of fatty material on the surface of the aqueous phase that should be removed. Transfer the clear supernatant to a fresh tube and proceed with step 2. Recover the high molecular mass DNA from the pellet by following DNA Isolation, steps 2 and 3.
