Glutathione in the red blood cells of embryonic mice.
A micro-method for the determination of red blood cell glutathione levels has been developed. It has been shown that, in order to obtain true values of glutathione concentrations within red blood cells, it is necessary to correct for loss of labelled glutathione and also to take account of the time taken to complete the analytical procedure. Glutathione is the major small molecular weight thiol present in embryonic red blood cells. The glutathione to haemoglobin ratio is maintained at 0.6 from 13 days gestation to adulthood in the mouse. Decay of glutathione in both adult and embryonic red blood cells can be avoided by incubation of the red blood cells in glucose containing buffers.
