Production and use of multimeric hemoglobins |
| abstract |
The present invention relates to multimeric hemoglobin-like proteins wherein two or more tetramers or pseudotetramers are covalently bonded. Between any pair of covalently linked tetramers, the covalent linkage may take the form of a crosslink between two cysteine residues of different polypeptide chain, or of a peptide linker connecting the "carboxy most" residue of a globin-like domain of one tetramer with the "amino most" residue of a similar domain of a second tetramer. Preferably, the multimeric hemoglobin-like protein-containing composition is at least 50% monodisperse, more preferably, at least 95% monodisperse. Although free hemoglobin purified from natural sources may be polymerized by chemical crosslinking to increase halflife via increased molecular weight, and to reduce oncotic pressure, all such preparations are heterogeneous. Monodispersability can be achieved only by laborious purification. The present invention provides means of exerting strict control over the degree of polymerization of hemoglobin tetramers. The ability to strictly control formation of multimers will greatly facilitate purification and characterization of the final product and will reduce the chance of adverse reaction to minor components. It is also believed that a more mono-disperse composition will have greater consistency of clinical effect. |
