[0028] In one embodiment, the stabilizer is an amino acid ( e.g., an aromatic amino acid, e.g., tyrosine, phenylalanine, and tryptophan). In another embodiment, the amino acid is selected from the group consisting of glycine, arginine, and praline or combinations thereof. The amino acids may be present at a concentration of about 5-300 mM ( e.g., about 5 mM to about 280 mM, about 5 mM to about 260 mM, about 5 mM to about 240 mM, about 5 mM to about 220 mM, about 5 mM to about 200 mM, about 5 mM to about 180 mM, about 5 mM to about 160 mM, about 5 mM to about 140 mM, about 5 mM to about 120 mM, about 5 mM to about 100 mM, about 5 mM to about 80 mM, about 5 mM to about 60 mM, about 5 mM to about 40 mM, about 5 mM to about 20 mM, about 5 mM to about 10 mM, about 10 mM to about 300 mM, about 10 mM to about 280 mM, about 10 mM to about 260 mM, about 10 mM to about 240 mM, about 10 mM to about 220 mM, about 10 mM to about 200 mM, about 10 mM to about 180 mM, about 10 mM to about 160 mM, about 10 mM to about 140 mM, about 10 mM to about 120 mM, about 10 mM to about 100 mM, about 10 mM to about 80 mM, about 10 mM to about 60 mM, about 10 mM to about 40 mM, about 10 mM to about 20 mM, about 20 mM to about 300 mM, about 20 mM to about 280 mM, about 20 mM to about 260 mM, about 20 mM to about 240 mM, about 20 mM to about 220 mM, about 20 mM to about 200 mM, about 20 mM to about 180 mM, about 20 mM to about 160 mM, about 20 mM to about 140 mM, about 20 mM to about 120 mM, about 20 mM to about 100 mM, about 20 mM to about 80 mM, about 20 mM to about 60 mM, about 20 mM to about 40 mM, about 40 mM to about 300 mM, about 40 mM to about 280 mM, about 40 mM to about 260 mM, about 40 mM to about 240 mM, about 40 mM to about 220 mM, about 40 mM to about 200 mM, about 40 mM to about 180 mM, about 40 mM to about 160 mM, about 40 mM to about 140 mM, about 40 mM to about 120 mM, about 40 mM to about 100 mM, about 40 mM to about 80 mM, about 40 mM to about 60 mM, about 40 mM to about 40 mM, about 60 mM to about 300 mM, about 60 mM to about 280 mM, about 60 mM to about 260 mM, about 60 mM to about 240 mM, about 60 mM to about 220 mM, about 60 mM to about 200 mM, about 60 mM to about 180 mM, about 60 mM to about 160 mM, about 60 mM to about 140 mM, about 60 mM to about 120 mM, about 60 mM to about 100 mM, about 60 mM to about 80
