The effects of short term cold storage upon ATP and 2,3-BPG levels in the blood of euthermic and hibernating thirteen-lined ground squirrels Spermophilus tridecemlineatus.
1. Whole blood was collected from hibernating and euthermic ground squirrels. 2. Blood from hibernating animals had approximately 50% less ATP and 2,3-biphosphoglycerate (2,3-BPG) than did that from euthermic animals. 3. In euthermic blood subjected to in vitro cold storage, levels of ATP decreased to those observed in hibernators, but 2,3-BPG did not decline significantly. 4. During cold storage of hibernator blood, no significant changes occurred in levels of these organophosphates.
