For the determination of stroma content in SFH, two analytical methods were developed, the HPLC-UV for phospholipids and the enzyme immunoassay for blood group antigen. These analytical methods were applied to evaluate three representative SFH preparations. The 36,000 x g centrifugation method was shown to contain higher amount of stroma components. On the other hand, the BMM-40nm and the ultrafiltration method with a 100kd membrane was shown to remove more than 99.7% of phospholipids and almost all of blood group antigen from hemoglobin solutions. These results demonstrated that these analytical methods were very useful in evaluating any highly purified hemoglobin solutions.
