A procedure for decreasing the level of 2,3-bisphosphoglycerate in red cells in vitro.
The physiological adaptation to anemia and other hypoxic states includes an increase in the level of 2,3-bisphosphoglycerate (2,3-DPG) in the red cell. We suggest that the high level of 2,3-DPG may have adverse effects in vivo. It has been found that red cells incubated with glycolate lose 2,3-DPG at a rapid rate relative to controls. ATP is stable. Net 2,3-DPG synthesis is observed after the glycolate is removed from the cells suggesting that they are not harmed. The effect appears to be specific for glycolate since lactate, glyoxylate, glycerate, acetate, and citrate were without effect. This procedure could be used to assess the effects of decreasing the 2,3-DPG level to normal in the erythrocytes of sickle cell and other anemias.
