Degradation products of mannitol/gluconate peak at 4°C 30 days (A) and at 70°C 30 days (B). products. We succeeded in generating a number of such degradation products which were screened for in the original and stable refrigerated samples. The absence of such degradation products in those samples corroborates the stability of the dNCS solution under the most updated criteria defined by the Food and Drug Administration and the USP. Not only are the titers of its major components unaltered, but there are also no confounding degradation products.
