Hemoglobins D-Los Angeles (β121 Gin) and Aida (α64 Asn) were encountered in an Asian Indian, unassociated with any clinical manifestations. These hemoglobins had normal oxygen affinities and were stable to heat and isopropanol. The ratio ofαchain synthesis toβchain synthesis was close to unity. The identical change in isoelectric points of the two variants produced an interesting electrophoretic pattern.The coexistance of more than one hemoglobin variant in an individual or family has provided valuable
