Descripción general
Hemoglobin A2 (HBA2) is mapped to human chromosome 16p13.3.[1] HBA2 is a minor hemoglobin component and comprises of two α and δ chains.[2]
Hemoglobin is the major component of red blood cells, and is responsible for their red color. Its normal concentration in erythrocytes is 34%. Hemoglobin is the most important respiratory protein of vertebrates by virtue of its ability to transport oxygen from the lungs to body tissues, and to facilitate the return transport of carbon dioxide.
has not been tested for functional equivalence against native preparations (unlyophilized ferrous hemoglobins).
Aplicación
Hemoglobin A2 was used in the determination of fetal hemoglobin by time-resolved immunofluorometric assay.[3]
Acciones bioquímicas o fisiológicas
Elevated levels of Hemoglobin A2 (HBA2) is observed in patients with β-thalassemia trait.[2]
Envase
Package size indicates the amount of hemoglobin as determined by the procedure of Drabkin, D.L., J. Biol. Chem., 164, 703 (1946).
Reconstitución
When reconstituted with buffer, gives >90% ferrous hemoglobin.
