Abstract
This study describes a highly sensitive and simple method of 169Yb tracing to investigate the uptake of Yb3+ in mouse erythrocyte. The amounts of Yb3+ absorbed by erythrocyte, membrane and cytoplasm at different time were determined after erythrocytes were incubated with 1.0.10-6 mol.l-1 169Yb3+ solution at 37°C. The results indicated that Yb3+ absorbed on the membrane was transferred promptly to the cytoplasm during the separation process. The observation of a very low level of Yb3+ in the cytoplasm could not lead to a verdict that Yb3+ could travel across the erythrocyte membrane [ABSTRACT FROM AUTHOR]
