    Abstract: Human interferon-beta.sub.2.sbsb.A and interferon-beta.sub.2.sbsb.B are produced in purified form by recombinant DNA techniques. Two separate human genes have been identified which code for the production of IFN-.beta..sub.2.sbsb.A and IFN-.beta..sub.2.sbsb.B, respectively. The sequence of IFN-.beta..sub.2.sbsb.A cDNA is established. These genes and cDNA have been cloned into mammalian cells with an SV40 early promoter sequence and such genomic clones are capable of producing IFN-.beta..sub.2.sbsb.A and IFN-.beta..sub.2.sbsb.B. The anti-viral activity of such recombinant IFN-.beta..sub.2.sbsb.A and IFN-.beta..sub.2.sbsb.B is demonstrated as well as other biological activity identifying them as human interferons.

    Abstract: The present invention .relates to a process to isolate genetic material (DNA) containing the nucleotide sequence coding for interferon in human fibroblastic cells which comprises cultivating cells producing interferon when exposed to an inducer of interferon, exposing same to such inducer, extracting messenger RNA from said induced cells, purifying the interferon messenger RNA, transcribing the messenger RNA into DNA and cloning the DNA in a suitable vector. Preferred cells are human diploid foreskin cells. The invention further relates to a process for engineering a bacterial strain to produce interferon polypeptide which comprises introducing a cloned interferon DNA into a suitable vector-carrier. A preferred vector-carrier is E. coli. The invention also relates to the mRNA of human interferon in highly purified form, to the mRNA of human interferon in .beta.1 highly purified form, to the mRNA of human interferon in .sym.2 highly purified form, to the DNA coding for a polypeptide having interferon activity, insertable in a vector, such as plasmid pBR322, and also to human interferon .beta.1 in highly purified form, and human interferon .beta.2 in highly purified form.

    Abstract: The invention concerns the production of the human fibroblast interferon, IFN-.beta.1 by cells of mammalian origin which are capable of constitutively expressing a DNA sequence encoding for IFN-.beta.1, producing the IFN and secreting it into the surrounding culture media.A specific embodiment of the invention comprises a methotrexate resistant chinese hamster ovary cell containing one or more pSVEIF molecules. The pSVEIF molecule contains a DNA sequence encoding for human INF-.beta.1 fused about 60 base pairs downstream from SV40 early start gene. The cell is capable of constitutively expressing the sequence encoding IFN-.beta.1, producing IFN-.beta.1 glycoprotein and secreting it into the surrounding medium.The invention also concerns methods of producing IFN-.beta. by culturing and growing the cells of the invention, and isolating and purifying the IFN-.beta.1 product.
