Abstract : Whole blood, red cell, and plasma preparations were stored at room temperature, refrigerated, and frozen. Samples were assayed over a 50-day period using the technique of constant-pH titration (pH-Stat). At least 90% of the cholinesterase activity in the whole blood and plasma preparations was retained for 6 days at room temperature and over 6 weeks when refrigerated or frozen. Red cell preparations retained 90% activity for less than 12 hours at room temperature, for up to 3 days if refrigerated, and up to 6 weeks when frozen. (Author)
