Abstract
The present invention relates to a method for the production of a substantially protoporphyrin IX free hemoglobin solution comprising: rapidly heating a crude protoporphyrin IX-containing hemoglobin solution for a relatively short time and at a relatively high temperature to reduce protoporphyrin IX-containing hemoglobin to insignificant levels in said protoporphyrin IX-containing hemoglobin solution.
