Biopure Corp. is developing a human blood substitute called Hemopure. Unlike donated human blood that needs to be refrigerated and expires after a short period of time, Hemopure is shelf stable and can be stored for two years or more. Also, it does not need to be matched to a person’s blood type. These factors make it wellsuited for trauma cases where blood must be transfused at an accidentsite or on the battlefield.
