An isolation procedure for the native alpha chain of bovine hemoglobin. A study of the functional properties of this chain and its hybrid with the human beta chain.

In this paper we present a procedure for the isolation of the native bovine alpha chain. The method is based on affinity chromatography. The results show that the ligand-binding properties of the bovine alpha chain are almost identical to those of the human alpha chain. The hybrid alphaB2 betaH2 prepared by mixing bovine alpha chains and human beta chains shows ligand binding properties similar to those of human hemoglobin and different from those of bovine hemoglobin.
