In order to purify a recombinant IFNβ-1b from endotoxins and host cell proteins, we have compared micellar and phenolic extraction procedures. It was shown that all contaminants were only effectively eliminated by the water-phenolic extraction. The conditions for obtaining of three phases, aqueous with LPS, phenolic with IFN and water-insoluble with the E. coli residual proteins, were selected. IFNβ-1b was then completely purified from the host cell proteins by RP HPLC.
Key words: endotoxins, extraction, interferon, phenol, RP HPLC, Triton X-114.
