Abstract: | Polyethylenglycol 4000 was used in a combined process of fractionation at normal temperature for preparing gammaglobulin and albumin in a heat denaturation process. Albumin can be gained from human plasma with a high yield and purity by using a heat procedure at the presence of polyethylglycol 4000 and sodium octanate at 75 degrees C. The concentration of polyethylglycol 4000 varies during this heat procedures from 3-10% W/V. |
