[Name] Dextran-Haemoglobin [Sponsor] Dextro-Sang Corp [Description] 
Currently in veterinary trials. Created by the Dexto-Sang Corporation, Dextran-Haemoglobin is a conjugate of the polymer dextran with human haemoglobin molecules. The safety of dextran has already been established, due to its wide use as a plasma volume expander. Conjugation of haemoglobin to dextran increases its half-life inside the body, and prevents tissue damage that occurs with free haemoglobin from processing by the kidneys and exit into the extracellular space.
