Abstract
A murine model of sickle cell disease was tested by studying the polymerization of hybrid hemoglobin tetramers between alpha mouse and human beta S or beta S Antilles chains were prepared from Hb S Antilles, which was a new sickling hemoglobin inducing a sickle cell syndrome more severe than Hb S. The hybrid molecules did not polymerize in solution, indicating that the mouse alpha chains inhibited fiber formation. Consequently, a mouse model for sickle cell disease requires the transfer and expression of both alpha and beta S or beta S Antilles genes.
