Abstract
RED cells of patients heterozygous for Hb A and the unstable haemoglobin, Hb Köln (FG5 Val→Met)1 contain only 10–15 per cent of the abnormal haemoglobin. This was found to arise from defective synthesis of the abnormal β Köln chain2–4, and not from its removal from cells by Heinz body formation. The techniques used in these studies might, however, have caused denaturation of Hb Köln and produced falsely low values for the proportion of Hb Köln synthesized. The relative rates of synthesis of Hb A and Hb Hammersmith (CD1 Phe→Ser)5, another unstable haemoglobin, have now been studied, using identical techniques, to test the validity of the Hb Köln experiments and to compare the synthesis of Hb Hammersmith with that of Hb Köln.
