1. A hemoglobin elution-staining procedure has been developed for distinguishing embryonic chick red blood cells from adult chicken red blood cells. 2. Adult hemoglobin is eluted from red blood cells with 1.9 M potassium phosphate buffer, pH 7.2; whereas, embryonic hemoglobin is retained within the cells and gives positive staining with erythrosin B. 3. The hemoglobin elution-staining pattern during development can be correlated with two embryonic hemoglobins as detected by polyacrylamide gel electrophoresis. 4. The series of red blood cells staining with erythrosin B correspond to the primary erythrocyte series suggesting that hemoglobin expression during development is correlated with different cell populations.
