Homozygous Hemoglobin C

Abstract
FIVE separate types of human hemoglobin have been described.¶ These have been differentiated by variations in certain physicochemical properties.2 3 4 5 They are classified according to the accepted system of nomenclature6 as Type A (normal adult), S (sickle cell), F (fetal) and two more recently recognized abnormal varieties (C and D).¶Types A, S and C hemoglobin are readily differentiated by relative mobilities in an electric field. The electrophoretic mobility of Type D hemoglobin is similar to that of Type S hemoglobin, from which it can be differentiated by solubility studies.5 Type F hemoglobin has an electrophoretic mobility similar to that of . . .
