Purification Methods

Protamine sulfate is a strongly basic protein (white powder, see pK) used to precipitate nucleic acids from crude protein extracts. It dissolves to the extent of 1.25% in H2O. It is freely soluble in hot H2O but separates as an oil on cooling. It has been purified by chromatography on an IRA-400 ion-exchange resin in the SO 4 form and is washed with dilute H2SO4. Eluates are freeze-dried under high vacuum below 20o. This method is used to convert proteamine and protamine hydrochloride to the sulfate.
