Oxidation resistant il-2 muteins and their production, formulations containing such muteins, and dna sequences and expression vectors coding for such muteins and corresponding transformed host cells

Abstract

A biologically active reference (e.g. human) IL-2 (interleukin-2) protein is protected against oxidation by a method involving substituting a conservative amino acid for each methionine residue susceptible to chloramine T or peroxide oxidation and wherein additional, non-susceptible methionine residues are not so substituted.
