    摘要: Interferon can be recovered simply by contacting an aqueous solution containing interferon which is induced and produced from cells of human origin capable of producing interferon, with a siliceous substance to adsorb interferon on it and eluting the adsorbed interferon with an aqueous solution containing a nonionic surfactant, preferably further containing an acriflavine such as acrinol.

    摘要: A method of producing a heterologous protein in yeast is disclosed, which comprises transforming a yeast Saccharomyces cerevisiae with recombinant DNA comprising a promoter selected from the group consisting of a yeast promoter or a hybrid promoter derived from a yeast promoter, particularly a hybrid promoter containing the enhancer region of SV40 virus, and a gene coding for a heterologous protein such as HBsAg and Pre S-HBsAg, particularly full length Pre S-HBsAg culturing, the resulting transformed cells to express the gene coding the heterologous protein, and isolating the heterologous protein from the cultured medium. GAP-DH and PH05 promoters and miniaturized ones can be used as the yeast promoter. The expression of the full length Pre S-HBsAg is carried out in the same expression system as that for 2nd or 3rd Pre S-ABsAg.
