Abstract: Method for the abstraction of pure serum albumin from blood which includes the steps of separating the blood plasma from the solid constituents of the blood and isolating the dissolved non-albumin constituents from plasma, adding an albumin-stabilizer and treating such fluid with a lower aliphatic alcohol, whereby, the treatment is carried out at a volume concentration of alcohol of 7 to 14% in the presence of 0.001 to 0.1 moles of the stabilizer, at a temperature of from 60.degree. to 75.degree. C. and pH of from 4.5 to 7.5; the concomitant proteins, partly or largely denatured, are precipitated; the resultant solution containing pure serum albumin is separated from the precipitate at a temperature of from 1.degree. to 30.degree. C., preferably at room temperature.

Abstract: A process for providing gamma globulin with improved intravenous compatibility. In the process, gamma globulin precipitated from blood or blood products is dissolved in an aqueous solution containing a hydrocolloid. The hydrocolloid is capable of forming a lyophilic sol. Gamma globulin is then precipitated from the solution to provide gamma globulin having improved intravenous compatibility.
