Localization of the haptoglobin α and β genes (HPA and HPB) to human chromosome 16q22 by in situ hybridization

Abstract
Human haptoglobin (Hp) is a protein that binds free hemoglobin and circulates in plasma of vertebrates as a tetrachain (αβ)2 structure. This study maps HPA and HPB, the genes encoding the Hp α and β chains to human chromosome band 16q22 by in situ hybridization.
