The present invention relates to blood products, and more particularly to compositions comprising a modified oxygenated hemoglobin having a high affinity for oxygen and methods for making such compositions. Such compositions according to the present invention have better stability to auto oxidation and superior oxygen carrying characteristics.


The present invention relates generally to methods of preserving an organ for transplantation. Specifically, the present invention is directed towards treating an organ with a hemoglobin-carbon monoxide complex to preserve the organ before transplantation.

PEGylated diaspirin-crosslinked hemoglobin conjugates having high oxygen affinity are described which have enhanced nitrite reductase activity to deliver oxygen, carbon monoxide, nitric oxide or mixtures thereof to tissues to treat various diseases and conditions.


The present invention relates to compositions for delivering carbon monoxide (CO) to cells using heme proteins as carriers. In one embodiment, the present invention relates to the use of MalPEG surface modified hemoglobin to deliver CO to cells.


The present invention relates to compositions for delivering nitric oxide (NO) to cells using heme proteins as carriers. In one embodiment, the present invention relates to the use of MalPEG surface modified hemoglobin to deliver NO to cells.


The present invention relates generally to methods for delivering oxygen to tissue and reducing nitrite to nitric oxide in the microvasculature. Specifically, the present invention is directed towards using a deoxygenated pegylated hemoglobin conjugate having enhanced nitrite reductase activity to deliver oxygen to tissues.

The present invention relates generally to polyethylene glycol (PEG) conjugated hemoglobins made by conjugation of succinimidyl-valerate activated polyethylene glycol to primary amines and N-terminal valines of the hemoglobin.


The present invention relates generally to a packaging system for preserving a nonoxygenated hemoglobin based oxygen therapeutic agent. More specifically, the present invention relates to a transparent overwrap packaging system comprising a primary product contacting package, a secondary package comprising a multilayer high barrier oxygen overwrap.


The present invention is a method for preparing stable HBOC solutions. Specifically, the method comprises the steps of deoxygenating a PEG-Hb conjugate and adding one or more antioxidants during or following the deoxygenating step to form a stabilized PEG-Hb conjugate. The Hb in the PEG-Hb conjugate is not crosslinked and the stabilized PEG-Hb conjugate has a p50 less than that of native SFH from the same animal source when measured under the same conditions. Specifically, the p50 is 62 mmHg or less than 10 mmHg.
