title: Purification of human lymphoblastoid cell-derived interferon-alpha by controlled-pore glass bead adsorption chromatography and molecular sieving.
abstract: Human lymphoblastoid cell-derived interferon-alpha has been purified by a combination of chromatography on controlled-pore glass 350, gel filtration on Ultrogel AcA 54 and hydrophobic chromatography on Phenyl-Sepharose CL-4B. Specific activities of greater than 10(7) units/mg have been obtained. Controlled-Pore Glass has the advantages of accommodating large volumes of induced medium in an "in-line" process giving high recoveries of interferon and removing most of any contaminating DNA.
