Abstract

A human hemoglobin with four distinct electrophoretic components was observed in an individual with leptocytosis and reticulocytosis. Three of the components were the previously reported hemoglobins A, C and G. The fourth (Porter) with a mobility of zero on conventional paper electrophoresis in alkaline buffer of pH 8.6, appears to be a new component arising as a result of the random association of the other two abnormal components.
