ABSTRACT:
The present invention concerns a method and compositions of matter useful for the method of making, in transgenic animals, a human hemoglobin that is more stable and more readily purified from the endogenous hemoglobins of the transgenic animal than hemoglobin A. The hemoglobins produced by the invention include hemoglobin A.sub.2, which is an .alpha..sub.2 .delta..sub.2 tetramer, as well as other hemoglobins having similar properties to hemoglobin A.sub.2 and have .beta./.delta. chimeric globins. The specification discloses a chimeric gene, encoding a human .delta.-globin that is expressed in transgenic animals at levels approximating the level of expression of the .alpha. or .beta. globin.
