Abstract

Transgenic, recombinantly cross-linked polymeric human hemoglobins suitable as cell-free blood substitutes have been produced. A plurality of DNA constructs have been designed for efficient expression of modified human hemoglobins in the erythrocytes of the non-human transgenic animals. Substantially pure, non-immunogenic, artificial human hemoglobins are then easily obtained from the erythroid cells of the transgenic animals.
