Oxidation-resistant interferon-beta muteins and their production; formulations containing such muteins.

摘要

A biologically active reference (e.g. human) IFN-Beta 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, where additional, non-susceptible methionine residues are not so-substituted.
