title: Reversed-phase chromatography of interleukin-2 muteins.
abstract: Human recombinant interleukin-2 (IL-2) and related species have been characterized by chemical modifications, tryptic digestion, and cyanogen bromide digestion. The oxidation states of the cysteines and methionines in several IL-2 muteins have been determined. Reversed-phase high-performance liquid chromatography allowed us to distinguish the modifications in these muteins and to correlate retention behavior with their structure.
