The separation of cells with different ages from erythrocyte populations of adult rats and young or adult chickens have been achieved by counter-current distribution (CCD). A thin-layer CCD apparatus has been employed. Erythrocytes from blood samples taken at different times after 59Fe i.p. injection were separated by CCD. By compilation in a "composite curve" of the hemoglobin and radioactivity CCD profiles obtained for each erythrocyte population, the distribution of cells according to age can be inferred. Young erythrocytes of rats are located at the right part of the CCD curves, while older cells are distributed towards the left. An opposite distribution has been found for erythrocytes from adult or young chickens. As a first attempt for the application of the CCD procedure to the assay of enzyme activities, it was found a decrease in phytase activity as the age of chicken erythrocytes increases and an increase in phosphoglycerate kinase and phosphofructokinase as the age of rat erythrocytes increases.
