ABSTRACT:
The described invention relates to an essentially stroma-free hemoglobin composition evidencing properties suitable for use as a universally applicable blood plasma expander and to a method for the preparation thereof. Typical, of these properties are desirable oxygen affinity values, desirable vascular retention time and substantial absence of toxic side effects. The described composition comprises human hemoglobin cross-linked intramolecularly through the beta-chains and polymerized with glutaraldehyde. Intramolecular cross-linking is typically effected with 2-nor-2-formylpyridoxal 5-phosphate or a bis-pyridoxal polyphosphate.
