Abstract
This investigation is concerned with the kinetics of the reciprocal relationship between sheep hemoglobin (Hb) A and Hb C formation in response to anemia. The relative synthesis of the hemoglobin types was assessed at various times in bone marrow erythroid cells incubated in vitro with 59Fe. The changeover from Hb A to Hb C formation lagged by about 3 days behind the development of anemia and was complete within about 11 days. After recovery from anemia the reciprocal change back to preanemic conditions proceeded at a much slower rate, Hb C formation gradually declining to unmeasurable levels over about 25 days.
