Modifications of the Cohn techniques are the methods of choice for the preparation of dilute albumin (PPS) and ϒglobulin solutions on an industrial scale. For the manufacture of refined albumin solutions, however, considerable labour and material is saved if crude, ethanol-precipitated fractions are heated in the presence of stabilisers in order to purify the albumin. The technique is simple and cheap, and yields a safe product of high quality. Bacterially contaminated and highly haemoglobinized plasma can be successfully heat-treated.
