The authors propose a method of using liquid heat treatment and polyethylene glycol (PEG) to separate a type of intravenous immunoglobulin (IVIG-H). The key points are as follows: Component II (IgG for intramuscular injection) or component II + III (crude IgG) was dissolved in cold distilled water and centrifuged (20000 g) at 2 ° C for 20 minutes. The supernatant (containing about 5% IgG and 2% ethanol,
