Stabilization of water-containing solutions or lyophilizates of proteins and peptide against non-enzymatic deamidation degradation reactions at asparaginyl or glutaminyhl residues is achieved using organic anions, such as saccharin, benzenesulfonic acid, gentisic acide or N-acetyltryptophan which have a pKa within the range of 0.5 to 3.5 |
