Claim 7:
8. A method for preparing a red blood cell (RBC) sample useful for determining RBC storage quality, the method comprising:
obtaining a sample of stored blood from a blood donor, wherein the sample comprises at least one marker selected from the group consisting of aspartate, glycylleucine, trans-4-hydroxyproline, thymidine, isoleucylglycine, gamma-glutamyltyrosine, valylglycine, N6-acetyllysine, glutamine, and N-acetylglycine;
contacting the sample with a reagent to generate a complex between the reagent and the at least one marker;
detecting the complex between the reagent and the at least one marker; and
measuring a level for the at least one marker, wherein the level of the at least one marker is positively correlated or negatively correlated with RBC storage quality.
