An improved process for recovering and purifying lipophilic recombinant proteins such as human beta -interferon and interleukin-2 from their hosts yields a protein preparation which may be formulated into a stable pharmaceutical composition having a therapeutically effective amount of the biologically active recombinant lipophilic protein dissolved in a non-toxic, inert, therapeutically compatible aqueous-based carrier medium at a pH of 6.8 to 7.8 which medium also contains a stabilizer for the protein, such as human serum albumin, normal serum albumin and human plasma protein fraction.
