Plasma proteins were fractionated with polyethylene glycol (PEG-4000) and the effects of pH, ionic strength and temperature were examined. Fractionation with 15% PEG was the most suitable for obtaining a precipitate containing mainly IgG, and a supernatant containing chiefly albumin. These fractions may then be purified further.
用聚乙二醇（PEG - 4000）对血浆蛋白进行分级分离，并研究了pH、离子强度和温度的影响。用15%的PEG进行分级分离最适合获得主要含IgG的沉淀物和主要含白蛋白的上清液。然后可对这些级分进一步纯化。
