Abstract
A solution for blood cell storage having sugar-containing blood cell nutrients therein and additionally containing a magnesium or calcium L-ascorbate-2-phosphate salt is taught. The magnesium and calcium L-ascorbate-2-phosphate salts remain stable below pH 7 and thus permit sterilization of the solution at a pH at which degradation of both the L-ascorbate-2-phosphate salt and the nutrient sugar present in the solution is substantially avoided.
