title: Rapid desalting of ammonium sulfate solutions by hydrophobic interaction chromatography.
abstract: Open-air hydrophobic interaction chromatography with alkyl carbon functional groups coupled to agarose beads has been used to desalt large volumes of ammonium sulfate-fractionated bacterial cell lysates. The protein of interest can be simultaneously desalted and concentrated in less than 4 h, and the yield is significantly better than that obtained by the standard technique of precipitation, centrifugation, and dialysis.
