Abstract
Solutions of mutant hemoglobins having a lower oxygen affinity than that of native hemoglobin are used as blood substitutes. The mutant hemoglobins are preferably obtained by recombinant DNA techniques. Both alpha and beta globin chains can now be so prepared, making possible the production of wholly artificial hemoglobin, whether conventional or mutant in form. Solutions of wholly artificial hemoglobins are also used as blood substitutes.
