Protein salt out
WebUse a buffer such as 50 mM HEPES or Tris to minimize the acidifying nature of ammonium sulfate. Use analytical grade ammonium sulfate since lower grades typically exhibit … Initial salting in at low concentrations is explained by the Debye–Huckel theory. Proteins are surrounded by the salt counterions (ions of opposite net charge) and this screening results in decreasing electrostatic free energy of the protein and increasing activity of the solvent, which in turn leads to increasing solubility. This theory predicts that the logarithm of solubility is proportional to the square root of the ionic strength.

In these studies Hofmeister discovered that the addition of salt decreases the solubility or “salts-out” the protein, and, that the efficacy of salting-out depends on the nature of the salt.

The concentration must be very high to precipitate proteins; therefore very soluble salts are generally used for protein precipitation (Hofmeister series).
